摘要
光催化裂解水产氢是缓解能源危机和环境污染两大难题最有前景的技术之一.石墨相氮化碳(g-C3N4)以其合适的带隙宽度、丰富的活性位点和成本低廉等优点,近年已成为极具有应用前景的光催化材料.然而,单一g-C3N4的可见光响应范围窄、电子-空穴复合严重、光催化产氢效率低等问题制约了其在光催化领域的应用.对g-C3N4进行形貌调控、表面改性、元素掺杂、构建异质结是改善其光催化性能的有效策略.介绍了 目前金属掺杂改性g-C3N4复合材料常见的制备方法,归纳了碱金属、过渡金属及稀土金属等非贵金属掺杂改性g-C3N4基复合材料的光催化水解制氢相关研究进展,旨在为光催化分解水制氢方面提供参考.
Abstract
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.
