Ordered modulation of electronic structure for efficient alkaline hydrogen oxidation

FlexMat, EarlyView.
We developed imc‐RuGa/hp‐hCN catalyst using in situ elastic spatial confinement method. This catalyst exhibits superior performance for the alkaline HOR, maintaining stable operation for 600 h at a 0.05 V versus RHE working voltage in 0.1 M KOH. It achieved 13 times greater mass activity than commercial PtRu/C.
