摘要： Graphite carbonnitride(g-C3N4),as an inorganic non-metallic semiconductor photocatalytic material,comprises a special energy band and crystal structure,which receives extensive attention in environmental governance and clean energy.However,the single-phase g-C3N4 has disadvantages of small response range to natural light,small specific surface area,few reactive sites,and high recombine efficiency of photoelectron-hole pairs,which limit its large-scale utilization in the field of photocatalysis.Transition metal sulfides have a special energy band structure,and excellent physical and photocatalytic properties,which show great development potential in photocatalytic applications.There were numerous researches generally focused on the construction of heterojunctions to solve the problems that catalytic materials has,such as narrow optical response range,low photocatalytic quantum efficiency due to the easy combination of carriers,short duration of carriers and insufficient reactive sites.Herein,the performance,structure design and reaction mechanism of the g-C3N4/transition metal sulfide photocatalytic materials were reviewed,the progress of the heterogeneous junction construction was discussed,and the development prospect of the g-C3N4/transition metal sulfide composite materials was prospected.
