摘要/Abstract

摘要： 催化剂的催化活性主要取决于活性位点的本征活性和活性位点数量.采用Ar/H₂热处理的方法以三聚氰胺(C₃H₃N₆)为N源进行掺N,通过调节H₂的体积分数以及C₃H₃N₆的量确定出最佳的制备工艺,制备了纳米多孔NiCoP/Ni₁₂P₅复合电极并产生大量的N空位.氮气20%,C₃H₃N₆为1.5%的2HN1.5-NCFP试样具有最佳的电催化活性,在10 mA/cm²的电流密度下析氢过电位为65.7 mV,Tafel斜率为67.3 mV/dec.

Abstract: The catalytic activity of catalyst mainly depends on the intrinsic activity of the active site and the number of active sites. The Ar/H₂ heat treatment method was used to mix N with melamine (C₃H₃N₆) as the N source, and the optimal preparation process was determined by adjusting the volume fraction of H₂ and the amount of C₃H₃N₆. The nanoporous NiCoP/Ni₁₂P₅ composite electrode was successfully fabricated accompanied by the generation of abundant nitrogen vacancies. The sample 2HN1.5-NCFPthat the volume fraction of H₂ is 20% and C₃H₃N₆ is 1.5% has the best electrocatalytic activity, with a hydrogen evolution overpotential of 65.7mV and a Tafel slope of 67.3 mV/dec at a current density of 10 mA/cm².
