Abstract
Photocatalytic technology is capable of converting CO2 into valuable hydrocarbons,providing a new way to solve the problems of fossil fuel shortage and global warming.However,conventional semiconductor photocatalysts are limited by the small specific surface area and insufficient CO2 adsorption capacity.g-C3N4 has attracted much attention due to its non-toxicity,high stability and low-cost.Although the photocatalytic efficiency of pure g-C3N4 is constrained by the fast complexation of photogenerated electron/hole pairs,small surface area and insufficient light absorption,the charge separation,surface area and light absorption of g-C3N4 can be significantly enhanced by forming heterostructure with large bandgap semiconductor.Such g-C3N4-based heterostructures include semiconductor-supported,carbon material-supported,non-metal-supported and metal-organic frameworks-supported,which show great potential in CO2 photoconversion.However,modified g-C3N4-based heterostructures still face challenges and require innovation on research and design.So,this review emphasizes the importance of g-C3N4-based heterostructures in environmentally friendly and sustainable approach to CO2 reduction.关键词
