Recent Progress in Doped g-C₃N₄ Photocatalyst for Solar Water Splitting: A Review

Graphitic carbon nitride (g-C₃N₄) photocatalysis for water splitting is harvested as a fascinating way for addressing the global energy crisis. At present, numerous research subjects have been achieved to design and develop g-C₃N₄ photocatalysis, and the photocatalytic system still suffers from low efficiency that is far from practical applications. Here, there is an inspiring review on the latest progress of the doping strategies to modify g-C₃N₄ for enhancing the efficiency of photocatalytic water splitting, including non-metal doping, metal doping, and molecular doping. Finally, the review concludes a summary and highlights some perspectives on the challenges and future research of g-C₃N₄ photocatalysts.
