NiMoO4@MoO3/NF自支撑电极的制备及其析氢性能研究
Preparation of self-supported NiMoO4@MoO3/NF electrode and its hydrogen evolution performance
摘要
Abstract
Under the"dual carbon"goals,the rational design of efficient non-noble metal hydrogen evolution reaction(HER)catalysts is critical for advancing scalable water electrolysis.In this study,a self-supported NiMoO4@MoO3/NF electrode was synthesized in situ on nickel foam via a hydrothermal method.Its morphological structure,electronic properties,and HER catalytic performance were systematically investigated through comprehensive physicochemical characterization and electrochemical analyses.Structural analyses revealed a 3D hierarchical architecture constructed by interlaced NiMoO4 micro-nanorods and MoO3 nanoflowers.Valence state investigations demonstrated that the electronic interaction between Ni and Mo synergistically optimized the electronic environment of active sites.Electrochemical tests in 1 mol·L-1 KOH demonstrated that this electrode exhibits a significantly lower HER overpotential(η10=176 mV),a smaller Tafel slope(79.91 mV·dec-1),and a reduced charge transfer resistance(13.1 Ω)compared to monometallic counterparts.The electrode retained approximately 75％of its initial current density after a 10-hour stability test.This work provides a novel strategy for hydrogen evolution catalyst development through the combined optimization of bimetallic synergy and structural design.Future research should focus on its stability under industrial operating conditions.关键词
