摘要
铋系光催化剂作为重要的可见光光催化剂,因本体铋的光催化性能并不优越,故对其表面进行改性。形貌调控和表面改性能有效增强铋系光催化剂性能,总结了铋系光催化剂形貌调控和表面改性方面的研究进展,介绍超薄结构协同异质结的形成、分级结构和空心结构构筑、官能团和纳米颗粒修饰表面、调控表面缺陷及进行原位转化形成金属铋和含铋化合物等改进铋系光催化剂性能的方法,分析了光催化改性铋系化合物的未来前景和所面临挑战。
Lanthanide photocatalyst is an important visible light photocatalyst.Because the photocatalytic performance of bulk ruthenium is not superior,its surface is modified.Morphological regulation and surface modification can effectively enhance the performance of lanthanide photocatalysts.The research progress on the morphology control and surface modification of lanthanide photocatalysts is summarized.The formation,hierarchical structure and hollow structure of ultra-thin structural synergistic heterojunctions are introduced.The future prospects and challenges of photocatalytic modification of lanthanide compounds were analyzed by constructing,functionalizing and nanoparticle-modified surfaces,regulating surface defects and in-situ conversion to form metal ruthenium and ruthenium-containing compounds to improve the performance of lanthanide photocatalysts.
