A novel structure of quasi-monolayered NiCo-bimetal-phosphide for superior electrochemical performance
文献摘要：
Bimetallic transition metal phosphides(TMPs)as potential candidates for superior electrochemical per-formance are still facing great challenges in the controllable preparation of two-dimensional(2D)struc-tures with high aspect ratio.Herein,a novel structure of quasi-monolayered NiCo-bimetal-phosphide(NiCoP)has been designed and successfully synthesized by the newly developed process combined with ultrasonic-cavitation and phase-transition.This is the first time to break through the controllable prepa-ration of 2D bimetal-phosphides with a thickness of 0.98 nm in sub-nanoscale.Based on the advantages of 2D quasi-monolayer structure with dense crystalline-amorphous interface and the reconfigured elec-tronic structure between Niδ+/Coδ+and Pδ-,the optimized Ni5％CoP exhibits an outstanding bifunctional performance for electrocatalyzing both hydrogen evolution reaction and oxygen evolution reaction in an alkaline medium.Ni5％CoP presents lower overpotentials and voltage of 84 mV&259 mV and 1.48 V at the current density of 10 mA cm-2 for HER&OER and overall water splitting,respectively,which are superior to most other reported 2D bimetal-phosphides.This work provides a new strategy to optimize the performance of electrolytic water for bimetal-phosphates and it may be of significant value in extending the design of other ultrathin 2D structured catalysts.
