Abstract

Given the clean and inexhaustible solar energy from solar light,photocatalytic ammonia synthesis is extremely appealing.However,high electron-hole recom-bination rates and insufficient active sites severely limited N2 photoreaction reduction.Herein,we designed and fab-ricated FeCu alloy nanoparticles anchored on carbon nitride nanosheets with excellent photocatalytic ammonia synthesis performance.As a coupler between Fe and car-bon nitride,Cu promotes the separation of photogenerated charge carriers in carbon nitride under solar light irradia-tion,and renters the semiconductor a forceful electron donor for the Fe active sites.The accumulated electrons at Fe sites furtherly facilitated the adsorption and activation of the molecular nitrogen.Besides,the uniform dispersed FeCu alloy nanoparticles were on carbon nitride nanosh-eets enhanced the stability of photocatalytic nitrogen reduction reaction,making the artificial photocatalytic ammonia synthesis more sustainable for application.This work highlights that a direct electron transfer channel can be used to regulate the photochemical nitrogen fixation network.
