Graphitic phase carbon nitride(g-C_(3)N_(4))is a metal-free semiconductor that has gained attention as a promising candidate for sustainable energy production and conversion.This is due to its low cost,easy manufacturing,non-toxicity,high stability,and environmental friendliness,as well as its appropriate band gap(~2.7 eV).The excellent photophysical and chemical properties of the g-C_(3)N_(4) nanostructure,including its high surface area,quantum efficiency,efficient separation and transport of interfacial charges,and ease of modification using composite materials,have also made it a focus of research in recent years.In this review,we summarize the latest research progress on the synthesis,modification strategies,and photocatalytic applications of g-C_(3)N_(4) nanostructured materials.Additionally,we provide a summary of the challenges faced by g-C_(3)N_(4)-based photocatalysts in production and application,and provide a prospective analysis of the development potential of g-C_(3)N_(4)-based photocatalysts.
