Abstract

Herein, we report a multiple regulation strategy towards an all-in-one NiCuMo/MoO_x 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.
