摘要：

Endowing materials with specific functions that are not readily available is always of great importance, but extremely challenging. Co4N, with its beneficial metallic characteristics, has been proved to be highly active for the oxidation of water, while it is notoriously poor for catalyzing the hydrogen evolution reaction (HER), because of its unfavorable d-band energy level. Herein, we successfully endow Co4N with prominent HER catalytic capability by tailoring the positions of the d-band center through transition-metal doping. The V-doped Co4...
