I owe my life to the platinum based drugs Cisplatin and Platinol. I had stage 4 cancer that spread to my vertebrae. The cure nearly killed me, but doing nothing would have killed me in 18 weeks. I have enjoyed 11 years of an active life thanks to chemistry. Keep it up boffins!
This element was first publicly named "platina" by the military scientist and mine inspector Antonio de Ulloa described in 1745, but at least since 1690 by the spanish military Antonio de Ulloa and Luis Fermin Capitan Vallvey, after visiting the Popayan mint house, who described this "stone" as being a recurrent problem in the smelting of gold, a hard silver-like stone that could not be broken on an anvil and similar to silver, and was resistant to calcination so they called "platina". Even though Johnson and Mathey stated in 1982 that there is not sufficient evidence, there are written records in the Seville "archivo de Indias". Even Watson, credited with the naming, met Ulloa who was jailed when his boat was seized by the british and all his scientific papers diligently scrutinized. Even Watson refers at first to this metal with the same name Ulloa employed. Plata in spanish means silver and the -ina sufix generally denotes little.
It acts as a framework for a reaction. In a simplified explanation it holds one molecule in place while another molecule smashes into the molecule that is being held in place. The catalyst degrades simply because over time pieces of the catalyst get knocked off. The catalyst doesn't rust like iron would, pieces of the platinum coating simply get knocked off. Hope this helps!
Fiberglass is made by flowing molten glass into platinum 'spinners' that are cans with thousands of tiny holes that allow the glass to extrude through them using centrifugal force. This molten glass is very corrosive to all other materials. Each spinner weighs ~25 lbs, accounting for >500,000 dollars in platinum alone. As an engineer, I regard platinum as the only material choice for many electro-chemical & noncorrosive, high-temperature applications. It's amazing stuff!
In the laboratory where I work we use a lot of platinum in the form of platinum crucibles. We use platinum because it doesn't react with our samples when we prepare them in a flux at 1250C and pour the molten mixture in platinum moulds to make glass beads that are very homogeneous and we can then measure them on our XRF. We recently had to weight all the platinum we have on our lab for insurence stuff, which came out to a little over 2kg of platinum. (I guess they won't miss a few gram :p)
Cool demonstration of the method used to operate model engines often used for radio control. The glow plugs used in the engines contain platinum, and the fuel is mostly methanol with some oil mixed in for lubrication. I always knew how it worked, but I had never seen a scientific demonstration performed like that.
Catalyst means it's not participating in the reaction as a reactant. This means that it does not lose mass but instead arranges the reactants it comes in contact with such that they react more efficiently. The reason it gets hot is because of the energy produced by the reactions.
the definition of a catalyst is that it provides an alternative route for the reaction to take place with a lower activation energy, without getting used up.
I have two internal combustion model aircraft and the glowplugs are essentially tiny hollow brass screws smaller than your fingernail, with a tiny, tiny coil of platinum inside, and an adaptor for an electric starter at the top. They cost about AU$8 each (which is around £5-£6 I think). Expensive stuff, especially because they wear out pretty quickly, around 2-3 flight hours if you demand a lot of performance from the engine.
my favourite metal, I use it as a paramagnetic metal to accompany magnetic matearials(Cobalt mainly) to produce thin films to observe what is called magnetic anisotropy. So far I have used Pt(Platinum very pure, very expensive), Pd(Palladium, see Pt) and Permalloy which is an alloy of Fe(iron) and Ni(nickel) and this is producing very interesting results.
It really depends on what type of converter it is, some use pellets of catalyzing material, and some use a "honeycomb" that the exhaust gases pass through. The platinum itself generally doesn't degrade, but there are other materials in the construction that do, but the most common cause of failure is contamination due to a poorly maintained engine, that overtaxes the CAT, or the material simply breaks loose, causing obstructions and/or a loss of catalytic efficiency.
Volume is the magnitude of the three-dimensional space enclosed within or occupied by an object, geometric solid, etc. In other words, the space it occupies. Meaning that 7 gr. (by weight) of a denser mass is going to occupy less space, which means less amount by volume. Example: 1 lb. of lead vs. 1 lb. of feathers. Which occupies more space? Their weight is the same, but you need a "boat load" of feathers to make a pound and a very small amount of lead, for it's heavier (denser).
Great video! It helps to explain how hobby glow engines can keep running, even after you remove the initial source of electric current (glow plug battery starter.)
Platinum just speeds up the reaction; it doesn't actually make the reaction go farther in one direction or the other. So if you have the reaction with ammonia and nitric acid, you will get the same amounts of products and reactants at the end no matter what, but with platinum as a catalyst it will just get to that point faster.
@blenderpanzi q catalyst is something used to speed up a reaction. It does not effect the quilibrium and only lowers the activation energy required to start the reaction.
@cowboy219 a catalyst doesn’t get used up in the reaction, its just a steppingstone for the other reactant. I think eventually (years and years) the platinum will mechanically break down though due to the heat, this is why catalytic converters need changing every so often.
so in order for the reactions to occur the reactants need to collide in the right amounts in the correct orientation for the product to be formed. platinum like other catalysts and enzymes provide a surface to "hold" the molecules in the correct orientation as well as increase the time in which the collision can occur.
The latter is the definition of a catalyst. Something that takes part in the reaction and then reappears in the products. IE: A+B+C(catalyst)->D+E D+E->F+C Note that it initially is used up, but then reappears as a product. That would be a catalyst (or at least that's my understanding of it).
Catalysts are just elements with alot of 'free' electrons in the outer shell which can be 'borrowed' in the presence of other reactions. They assist these other reactions.
my very excentric chemistry proffesor died when I was there and when they looked through his desk they found a puddle of mercury and a platinum bar worth about £50000 that had been in his desk for about ten years unlocked.
The latter is basically correct. :) The catalyst participates in the reaction, often helping the other two-or-however-many reactants get together. This makes the reaction more likely to occur than it would in the absence of the catalyst. The end products are still the same, leaving the catalyst behind.
@megaverse Platinum is an element meaning it exists as atoms not as molecules. Thus, to get a block of Pt metal, you would somehow need to find a bunch of Pt atoms and get them to stick together. But the essential problem still remains: Pt atoms are rare. But if you were asking whether it's possible to construct Pt atoms by amassing subatomic particles (electrons, protons, neutrons) I doubt it. But it might be possible to do something of the sort via nuclear reactions as has been done with gold.
"I'd better get a model". The quintessential nutty professor and his squeaking bag of teaching tools! Love these videos - never knew chemistry could be such fun.
The amount of atoms on an element is called the atomic number. This tells you the atomic weight of an element and you can see this in the periodic table... not the same as Volume, although there's a relationship between them, for one affects the other.
Fantastic!! I had quimotherapy with Platiran (I think it´s a trade mark for Cisplatin) and by that time I was told it was derived from Platinum but I had no ideia how it works. Thank you very much.
@PowerOfTheMirror there are 2 types of catalysts..a homogeneous and a heterogeneous catalyst. The one you read on wiki was most probably the homogeneous where the catalyst is of the same state as the reactants and thus being able to speed up the reaction by providing an alternative pathway for the reaction. The heterogeneous catalyst however, is of a different state as the reactants for example the platinum in the video. Methanol and oxygen are both in the gaseous state while platinum is a soli
@JossJossJoss1 it does react to a few think such as the methanol atmosphere, where the molecules coming into contact with the platinum fibers,while heating the fibers, create the highly combustible vapors. so as it is very nonreactive it does react with some things.
@mvszao because like almost all metals that we mine, there are occasional inclusions and grains, possibly even the rare small nugget in the unprocessed ore. Especially in the case of platnium, which generally comes from placer mines.
@stardude692001 You are right, fuel isn't free and neither is mining in space but the potential rewards from mining the asteroid belt would be absolutely incredible.
On a side note, stainless steal (304) can be used in certain types of fuel cells to replace platinum and the losses in efficiency are essentially negligible. ...And there's plenty of stainless steal available. I'm not an expert in fuel cells but I have made a few rudimentary ones using stainless steal and have never seen any significant degradation of the metal. Do the developers know this? They should. it makes me lean towards the notion of a conspiracy--- oops! we can't use that word! ...of a concerted effort to keep the price of oil and the petrol dollar, high.
Another issue (aside from chemical reactivity) is that gold is quite soft. The platinum alloy that they use is hard enough, I think, that they don't risk rubbing or scratching off fractions of a gram when they pick it up.
Are you going to be doing an updated titanium video soon? I've got a titanium plate in my wrist and I think it would be cool to see how badass it is. Love these videos btw.
it just provides a nice surface for the reaction to occur, and lowers the needed activation energy, speeding up the reaction. As the video asserted, Pt is very nonreactive, and as a catalyst, it does not appear chemically in the reaction, just accelerates it!
ρ(density)= m(mass) / V(volume). According to this equation, if you take two objects of the same mass, but with different densities, the one with the highest density will be the one with the lowest volume. Therefore,he is right when saying that 7 gr. of platinum is less in VOLUME than 7 gr. of, for example, lithium, as lithium's density is lower than platinum's.
@grimace365 it doesn't create the combustible vapors, methanol is combustible all by itself. it is a catalyst for the natural reaction between methanol vapors and oxygen, and the accelerates the breakdown of methanol so much that it gets very hot, and eventually it gets hot enough to ignite the methanol vapors (in the oxygen/nitrogen environment that is every day breathing air) but it itself doesn't really react, there is no platinumoxide or anything like that created.
Could you explain what's happening on the platinum as a catalyst? Is it oxidizing and slowly evaporating like a tungsten filament would? Or is it just acting of a framework for the reaction and assisting in intermediate steps of the reaction and not losing mass?
@BlackSkullRacer613 Well, the amount of water in a liter of water varies depending on pressure, but the amount of platinum-iridium alloy in that cylinder doesn't. Presumably, that is why it was chosen as a standard?
@illustriouschin or bring one in to orbit earth because fuel isn't free. but yes I have heard some estimates that say one or two large asteroids being mined in earth orbit could drop gold to the price of silver, silver to the price of copper and copper to the price of iron, or proximately.
Don't worry, I'm quite sure our friend lohphat knows this fact very well, he had just hoped that they made the term "catalyst" more clear in this video.
I remember I saw a fake documentary about dragons. The theory there was that dragons scratched their teeth on rocks containing platinum, and exhaling a gas (I don't remember what, might've been pure oxygen), and this was the way they could breathe fire. If only...
and platinum is enormously dense, so an ounce is just slightly larger than a cubic centimeter (the the dice in monopoly are just over 4 cubic centimeters)
It would be lovely to see a video about the haber process. I worked on a boiler once, it took advantage of the heat generated down stream from a similar reaction. Might have had something to do with making nitric acid?? Platinum was one of the catalysts, ammonia was involved. Forgive me I’m a metal tradesmen, no chemist 🙃
Important question (I think) You can use platinum for ammonia to create nitric acid and you can use platinum to go reverse what is it that determine how it will react. Appreciate very much any answer on this.
You know where you can find a whole hell of a lot of platinum? Asteroids. We need to get mining those things so we can take advantage of all the wonderful applications of this metal without running out so readily.
I like that even the professor considers 7am too early to be up for something.

it is such a boon to have periodic table of videos :)
Very creative and interesting videos that inspire a generation of (maybe) new Mendeleev's
I dare you to decompose hydrogen peroxide with platinum.
catalysts do not only speed up reactions but also slow them down
so to be precise you'd have to call it positive catalyst
Those methane molecule sounds at 6:52 are absolutely hilarious!!!

The word "catalyst" says it: a catalyst does not react.
It only speeds up the reaction between other elements.

Fantastic!! I had quimotherapy with Platiran (I think it´s a trade mark for Cisplatin) and by that time I was told it was derived from Platinum but I had no ideia how it works. Thank you very much.
It's assisting and not losing mass. The platinum is unchanged in the reaction.

Error in the video: the international standard kilogram is an alloy of platinum and iridium, not platinum and indium.
that's a nice demonstration of catalysis. I wonder if it will work with a normal platinum electrode instead of that fine mesh.
@Yourveryking
Didn't know about that stuff...thx for making my day!

@BlackSkullRacer613
Water's density varies with temperature, it evaporates, absorbs gases etc.
It was a catalyst. It heated up during the process then lit the methanol vapor.

I'd love a tour of Prof. Poliakoff's office. He's got some pretty cool stuff in there.
the professor has lost it... "like a little airplay, BRUURURURUUR, if you want an engine!"
Important question (I think)
You can use platinum for ammonia to create nitric acid and you can use platinum to go reverse what is it that determine how it will react. Appreciate very much any answer on this.
Thank you!

You know where you can find a whole hell of a lot of platinum? Asteroids. We need to get mining those things so we can take advantage of all the wonderful applications of this metal without running out so readily.
@flaluguna Yes we noticed that that's setting multiple screens in nVIDIA control panel.
This doesn't have much to do with the video, but was The Professor in Manchester yesterday? I'm sure I saw him at Oxford Road station.
Would the catalysis experiment work with platinum foil instead of gauze?
So how, exactly, does platinum, and other catalysts, help something react while not changing in any way?
