FeS@NiMoO4异质结构筑及电催化析氢性能研究
Exploring electrocatalytic hydrogen evolution performance of FeS@NiMoO4 heterojunction
摘要
Abstract
A FeS@NiMoO4 heterostructure electrocatalyst was successfully fabricated using a two-step hydrothermal method.NiMoO4 nanorods modified by FeS nanosheets can provide a larger specific surface area,exposing more active sites.The hetero-interface formed by FeS@NiMoO4 offers fast charge transfer channels,thereby achieving excellent electrocatalytic hydrogen evolution performance.The composition and morphology of the materials were characterized by X-ray diffraction,X-ray photoelectron spectroscopy,scanning electron microscopy,and transmission electron microscopy.The electrochemical properties were characterized using an electrochemical workstation.At a current density of 10 mA/cm2,the FeS@NiMoO4 exhibits a hydrogen evolution overpotential of 151 mV,a Tafel slope of 110 mV/dec,and good stability,demonstrating outstanding electrocatalytic hydrogen evolution performance.关键词
