📄 Abstract（原文）
Electrocatalytic hydrogen evolution under alkaline conditions offers a sustainable method for producing clean and renewable energy. Highly efficient and low‐cost catalysts are pivotal to the industrial application of this technology. In this work, nanoporous Cr‐doped Co2P catalyst prepared by electrochemical dealloying is reported as an efficient electrocatalyst for hydrogen evolution reaction (HER), achieving remarkable catalytic performance with the overpotential of 50 mV at 10 mA cm−2 in alkaline solution, along with impressive stability at a large current density of 500 mA cm−2. Experimental results reveal that the introduction of Cr alters the electronic state of Co2P, which facilitates the water dissociation for generating sufficient active hydrogen. This doping engineering would offer a new perspective for designing efficient HER electrocatalysts.
