摘要：

The present non-precious hydrogen-evolving electrocatalysts deliver high catalytic activity either in acidic or basic media but very few simultaneously exhibit superb catalytic efficiency and stability for hydrogen evolution reaction (HER) in a wide pH range, especially for pyrite-phase materials (e.g., CoS2, NiSe2), probably due to their high kinetic energy barriers of initial water dissociation process. Herein, we report a phase transition engineering of pyrite-phase porous NiSe2 into NiP1.86Se0.14 by heavy phosphorus doping, which performs e...
