These electrocatalyst structures were applied to the hydrogen evolution reaction (HER), which is the crucial cathodic reaction in water - alkali electrolyzers, which generate hydrogen by splitting water.

That's because a competing reaction, called the hydrogen evolution reaction (HER) or «water splitting,» takes precedence over the CO2 conversion reaction.

Hydrogen oxidation and hydrogen evolution reactions are two of the simplest electrochemical reactions, yet happen to be the backbone to developing critical clean energy technologies.

Although it is simple in theory, splitting water into hydrogen and oxygen is a complex process, requiring two separate reactions — a hydrogen evolution reaction and an oxygen evolution reaction, each requiring a separate electrode.

«Remarkably, simple treatment of the graphene - molybdenum oxides with sulfur, which converted the metal oxides to metal sulfides, afforded a hydrogen evolution reaction catalyst, underscoring the broad utility of this approach,» he said.

«Normally, a hydrogen evolution reaction is done in acid and an oxygen evolution reaction is done in base.
