Chemical Catalysts
Hydrogen peroxide will decompose into water and oxygen gas. Two molecules of hydrogen peroxide will produce two molecules of water and one molecule of oxygen. A catalyst of potassium permanganate can be used to speed up this process. Adding potassium permanganate to the hydrogen peroxide will cause a reaction that produces a lot of heat, and water vapor will shoot out.
The catalytic converter in a car contains platinum, which serves as a catalyst to change carbon monoxide, which is toxic, into carbon dioxide.
If you light a match in a room with hydrogen gas and oxygen gas, there will be an explosion and most of the hydrogen and oxygen will combine to create water molecules.
The Iron catalyst used in the Haber-Bosch process, which is the main industrial process for ammonia production. This process is critical for world wide fertilizer production and is a multi-billion dollar industry that enables massive scales of global crop production. The catalyst is typically iron promoted with K2O, CaO, SiO2, and/or Al2O3. The original catalyst for this process used osmium, but that element is too rare and expensive for industrial use.
Chromium on silica (Cr/SiO2), “The Phillips Catalyst”, is responsible for half the world’s polyethylene production.
Tungsten on silica (W/SiO2) is used for industrial scale olefin metathesis. See the Shell Higher Olefin Process (SHOP).
The Grubbs' catalysts (a series of transition metal carbene complexes) are used as homogeneous catalysts for olefin metathesis
Gold nanoparticle catalysts for low temperature CO oxidation.
Amorphous MoS2 for water splitting.
