摘要
The utilization of solar energy to drive energy conversion and simultaneously realize pollutant degradation via pho-tocatalysis is one of most promising strategies to resolve the global energy and environment issues.During the past decade,graphite carbon nitride(g-C3N4)has attracted dramatically growing attention for solar energy conversion due to its excellent physicochemical properties as a photocatalyst.However,its practical application is still impeded by several limitations and short-comings,such as high recombination rate of charge carriers,low visible-light absorption,etc.As an effective solution,the elec-tronic structure tuning of g-C_(3)N_(4)has been widely adopted.In this context,firstly,the paper critically focuses on the different strategies of electronic structure tuning of g-C_(3)N_(4)like vacancy modification,doping,crystallinity modulation and synthesis of a new molecular structure.And the recent progress is reviewed.Finally,the challenges and future trends are summarized.
