磷化镍钼电催化剂的制备及其析氢性能研究
Study on preparation of nickel-molybdenum phosphide electrocatalysts and its hydrogen evolution performance
摘要
Abstract
Currently,commercially available electrolytic water catalysts are primarily precious metal catalysts represented by platinum and iridium.However,issues such as limited global reserves and high cost of precious metal catalysts hinder their large-scale application.This study successfully synthesized a NiMoP electrocatalyst via a one-step calcination method and investigated the effects of varying metal phosphorus and molybdenum source additions on the material's morphology and electrocatalytic hydrogen production performance.The results in-dicate that the synergistic interaction between Mo and Ni in the bimetallic catalyst enhances charge transfer.The coupling between these two metals yields a richer electronic and geomet-ric structure compared to single-metal phase catalysts(MoP and Ni2P),effectively addressing issues such as the unstable catalytic performance of single transition metal phosphides.At a current density of 10 mn A/cmn2 in 1.0 M KOH,the NiMoP electrocatalyst exhibited an over-potential 206 mV and 121 mV lower than MoP and Ni2P catalysts,respectively,while main-taining stable operation for at least 40 hours.This research provides significant guidance for developing novel transition bimetallic electrocatalysts.关键词
