The state-of-the-art alkaline hydrogen evolution catalyst has a serious problem that hydrogen evolution primarily proceeds on the less active ruthenium single atoms instead of the more efficient small ruthenium nanoparticles. There is a need to develop a new catalyst that can improve the hydrogen evolution activity.

The less active ruthenium single atoms instead of the more efficient small ruthenium nanoparticles are used for hydrogen evolution. The strong oxophilicity of cerium needs to be utilized to drive the alkaline hydrogen evolution centers to the more active ruthenium nanoclusters.

The resulting catalyst delivers efficient alkaline HER and, importantly, sustains hydrogen evolution deep into the high‐current‐density regime with strong operational durability, addressing a key limitation of many PtNi‐based catalysts commonly evaluated only at low currents.
