Research progress in constructing functional Bi2O3 photocatalytic materials

摘要:

随着世界经济的快速发展，出现了严重的能源短缺和环境危机，光催化技术是缓解该问题的有效方案。氧化铋因其独特的层状结构和较窄的禁带宽度，具有潜在的可见光驱动光催化性能，逐渐成为环境能源科学领域的研究热点之一。本文概述了氧化铋光催化材料的研究现状，介绍了其构筑策略、去除成效以及主要机理，阐述了在光催化水环境处理、水分解制氢、固氮脱硫、杀菌消毒、二氧化碳还原、电池电极等环境能源领域的应用并做出了展望。

Abstract:

With the rapid development of the world economy, serious energy shortages and environmental crises have emerged, and photocatalytic technology is an effective solution to alleviate this problem. Bismuth trioxide, due to its unique layered structure and narrow bandgap, has the potential for visible-light-driven photocatalytic performance and has gradually become one of the recent research hotspots in the field of environmental energy science. This paper outlines the current research status of bismuth trioxide photocatalytic materials, and describes their construction strategies, removal effects and main mechanisms. Its applications in environmental energy fields such as photocatalytic water environment treatment, hydrogen production by water decomposition, nitrogen fixation and desulfurisation, bactericidal disinfection, carbon dioxide reduction, battery electrode, etc., are also described and prospected.
