Modification and Application of Bi2MoO6 in Photocatalytic Technology
【摘要】 目前,生态污染和能源短缺成为威胁人类生存的全球性问题,绿色、低碳的光催化技术对解决环境及能源问题具有战略性意义。作为三元奥里维里斯型(Aurivillius)化合物,Bi2MoO6凭借独特的层状结构引起研究者的广泛关注。然而,由于高的载流子复合率限制了其在光催化技术中的应用。本文重点总结概括对Bi2MoO6基光催化剂性能改性的策略,如表面结构调控、缺陷工程、金属沉积、构建异质结及光敏化处理。在诸多改性策略中重点论述Bi2MoO6基异质结的构建对光催化性能的影响。并对Bi2MoO6基光催化剂当前在光催化技术中面临的挑战及未来的发展前景进行展望,为加快Bi2MoO6基光催化剂的发展提供新思路。
【Abstract】 At present, ecological pollution and energy shortage have become global problems threatening human survival. Green and low energy consumption photocatalytic technology is of strategic significance to solve environmental disaster and energy crisis. As a ternary Aurivillius compound, Bi2MoO6 has attracted extensive attention of researchers due to its unique layered structure. However, the high carrier recombination rate limits its application in photocatalysis. This paper summarizes the strategies for modifying the performance of Bi2MoO6 based photocatalysts, such as surface structure tuning, defect engineering, metal deposition, heterojunction fabrication and photosensitization treatment. In many modification strategies, the influence of the construction of Bi2MoO6 based heterojunction on the photocatalytic performance has been mainly discussed. Finally, the current challenges faced by Bi2MoO6 based photocatalyst in photocatalysis technology are summarized, and the future development prospects are given, providing new ideas for accelerating the development of Bi2MoO6 based photocatalyst.
