Hydrogen production by dehydrogenation of formic acid on atomically dispersed gold on ceria.

Less is More: Atomically dispersed gold species catalyze the decomposition of formic acid through the dehydrogenation pathway at near-ambient temperatures. Gold on ceria is demonstrated to be an effective and stable catalyst. By using this catalyst, mechanistic insights are obtained that can lead to the use of trace amounts of gold to achieve robust and cost-effective catalysts.
