Graphitic carbon nitride (g‐C3N4)‐based photocatalysts are promising for photocatalytic water splitting to produce clean solar fuels due to their low cost, suitable band structure and excellent photocatalytic performance. This review focuses on the state‐of‐the‐art progress of the strategies for modifying g‐C3N4‐based photocatalysts toward efficient photocatalytic water splitting. In particular, we highlight the importance of interfacial engineering and nanostructural control to facilitating charge separation and migration. Other strategies including doping and defect engineering are also concisely discussed. Finally, the perspectives on the challenges and future development of g‐C3N4‐based photocatalysts are presented. It's time to split: This review focuses on the state‐of‐the‐art progress of the strategies for modifying g‐C3N4‐based photocatalysts toward efficient solar water splitting. In particular, the importance of interfacial engineering and nanostructural control to promote the charge separation and transfer is highlighted. This review should inspire the design of new types of g‐C3N4‐based photocatalysts for more efficient solar fuel production.
