Nanosheet catalyst discovered to sustainably split hydrogen from water

Now, scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have developed a new electrocatalyst that addresses one of these problems by generating hydrogen gas from water cleanly and with much more affordable materials. The novel form of catalytic nickel-molybdenum-nitride – described in a paper published online May 8, 2012 in the journal Angewandte Chemie International Edition – surprised scientists with its high-performing nanosheet structure, introducing a new model for effective hydrogen catalysis.

Very cool.

... and surprisingly, they didn't accidentally create cold fusion.

People tend to think of platinum and palladium catalysts, but there are a whole series of transition metals that show catalytic activity of one form or another.

Titanium dioxide semiconductors have also been looked at since the mid-70's for assisting photodissociation of water.

I threw together a cobalt compound and a molybdnium compound to make a cobalt molybdate catalyst for oxidizing hydrogen sulfide to sulfur dioxide, and I'm not a chemist.

Part of the key is the nanostructure, putting the catalytic points in the right geometry. They should be getting better at it these days.

Don't show it to Rossi. He will claim it was his idea, and that they are SNAKES!
