Multiple regulation towards an all-in-one NiCuMo/MoOx heterostructure for improving alkaline hydrogen oxidation

Herein, we report a multiple regulation strategy towards an all-in-one NiCuMo/MoOx heterostructure for the HOR, which exhibits ultrahigh HOR activity (j@0.05V = 4.63 mA cm-2) and excellent durability for almost 24 h for the synergistic regulation of Mo and Cu on the Ni electrode. This study provides a new strategy for designing efficient non-noble metal-based HOR catalysts.
