【Abstract】 Graphitic carbon nitride（g-C₃N₄）,with unique electronic structure,high stability,and visible-light-induced photocatalytic activity,has attracted considerable attention. The g-C₃N₄-based Z-scheme photocatalytic system can effectively lower the recombination rate of electron-holes and the utilization of light sources is improved. The reaction mechanism of photocatalytic water splitting and the applications of g-C₃N₄-based Z-scheme photocatalytic system in photocatalytic water oxidation,photocatalytic water conversion and photocatalytic overall water splitting are reviewed. Moreover,the future development of Z-scheme is forecasted.更多还原
