摘　　要：Graphitic carbon nitride(g-C_(3)N_(4))has been widely studied as a visible light responsive photocatalyst in recent years,due to its facile synthesis,low cost,high stability,and appropriate bandgap/band positions.In this review,we firstly introduce and compare various exfoliation approaches of bulk g-C_(3)N_(4)into ultrathin g-C_(3)N_(4)nanosheets.Then,many modification strategies of g-C_(3)N_(4)nanosheets are also reviewed,including heterojunction construction,doping,defect control,and structure design.Thereafter,the charge transfer mechanism in g-C_(3)N_(4)nanosheets based heterojunctions is present,e.g.,Z-scheme,S-scheme and other forms.Besides,the photocatalytic applications of g-C_(3)N_(4)nanosheets based photocatalysts are summarized including environmental remediation,energy generation and storage,organic synthesis,and disinfection.This review ends with a summary and some perspectives on the challenges and new directions in exploring g-C_(3)N_(4)nanosheets-based photocatalysts.
