Are there any known catalysts that can combine hydrogen and oxygen into water?

Does this type of reaction have a name? Trying to search for information, it seems to be all about splitting hydrogen and oxygen, is there any work on combining these and some catalysts that could be used?

    $\begingroup$ This looks like catalytic hydrogen combustion (CHC). Rarely needed, unless one needs to burn hydrogen in a more controlled manner without producing flames or explosion. I suggest searching Google Scholar with this keyword to get an idea what transition metals and their oxides are used in which cases. $\endgroup$ – andselisk Oct 27 '19 at 13:16
  • $\begingroup$ @andselisk "Rarely needed" unless you want to generate clean electricity. This is what fuel cells do. Using exactly this reaction. $\endgroup$ – matt_black Oct 28 '19 at 11:34

Not only is this possible it can be done while extracting electricity from the reaction. This is the key reaction in a hydrogen/oxygen fuel cell.

Fuel cells have been known for well over a century and Hydrogen oxygen fuel cells have been used commercially since the 1930s. Platinum is often used as a catalyst for the key reaction in the cells.


Platinum is a good catalyst for this reaction. This technique is well known. It has been developed in the 19th century by Döbereiner.
