Photocatalytic transformation of organic materials is widely known as one of the most favorable procedures to fabricate value-added compounds. Achieving considerable selectivity along with targeted conversion is the most challenging issue in these reactions and requires design and development of new photocatalysts. In this review, we summarized latest developments in photocatalytic synthesis of organic compounds over graphitic carbon nitride (g-C3N4)-based composites. Strategies including copolymerization, engineering the structure of photocatalyst, metal and nonmetal doping, design of heterojunctions and ternary nanocomposites based on g-C3N4 to progress photocatalytic activity were highlighted, with perspectives, challenges and future directions also discussed. © 2020
