Preparation of organic compound/g-C3N4 composites and their applications in photocatalysis

Photocatalysis based on the organic polymer semiconductor, g-C₃N₄, is a green technology, but effective energy conversion is still limited by the small light absorption range and high photogenerated carrier complexation rate of g-C₃N₄ photocatalysts. The introduction of organic molecules into the g-C₃N₄ backbone has become a design hotspot for optimising g-C₃N₄ performance. In this review, recent developments in the morphology of g-C₃N₄-based composites as photocatalysts, strategies for the preparation of organic compound/g-C₃N₄ composites and the applications of organic compound/g-C₃N₄ composites in photocatalysis are introduced. The perspectives on future directions of organic compound/g-C₃N₄ composites are discussed.
