英文摘要developing highly efficient and low-cost noble metal-free catalysts toward hydrogen evolution from water splitting is an attractive alternative strategy to solve the ever-increasing environmental contamination and energy demand. herein, a porous cop electrocatalyst with a concave polyhedron (cph) structure was facilely prepared by a topological conversion strategy using co-mof (zif-67) polyhedrons as the precursor. the morphology of co-mofs is well inherited by the as-prepared cop sample due to the multi-step calcination process at low temperature, which results in the formation of a porous structure. compared with the contrastive cop nanoparticles (nps), the obtained porous cop cph electrocatalyst exhibits a remarkably enhanced electrocatalytic performance with a current density of 10 ma cm(-2) at an overpotential of 133 mv and a superior durability for the hydrogen evolution reaction (her) in acid media. a small tafel slope of ca. 51 mv dec(-1) reveals a volmer-heyrovsky mechanism during the her. this work provided a new insight to fabricate morphology-controlled transition metal phosphides with a porous structure via topological conversion, which have importantly potential applications, such as electrocatalysis, photocatalysis and sensors, thanks to their porosity and controllability.
