Graphitic Carbon Nitride‐ B ased Photocatalysts

Graphitic carbon nitride (g-C 3 N 4 ) is a widely studied two-dimensional photocatalyst due to its visible light response, suitable band structure, good physicochemical stability, and easy preparation. However, its photocatalytic performance is limited by many factors, such as low specific surface area, high recombination rate of photogenerated charge carriers, and low surface catalytic reaction kinetics. In this chapter, the main progresses about g-C 3 N 4 -based photocatalysts are summarized, including preparation, photocatalytic applications, and major strategies for optimizing performance. The major challenges and prospects for g-C 3 N 4 -based photocatalyst are highlighted.
