Research progress on Photocatalytic Water Splitting Hydrogen Generation by Non-noble Droping Modified g-C3N4
Photocatalytic water splitting hydrogen generation is one of the most promising technologies for alleviating energy crisis and environmental pollution.Graphitic carbon nitride(g-C3N4)has become a promising photocatalytic material for applications in recent years due to its advantages of suitable bandgap width,rich reactive sites and low cost.However,the narrow response range to visible light,high reconbine efficiency of photoelectron-hole pairs and low efficiency of photocatalytic hydrogen production of g-C3N4 seriously restrict its application in the field of photocatalysis.The effective strategies to improve the photocatalytic performance of g-C3N4 are morphology regulation,surface modification,element doping and heterojunction construction.In this paper,the common preparation methods of metal-doped g-C3N4 and the related research progress in photocatalytic water splitting hydrogen generation are introduced,including alkali metal doping,transition metal doping,rare earth metal and other non-noble metal doping.This review also helps to provide insights for photocatalytic water splitting hydrogen generation.
