摘要
碳酸氧铋是一种典型的铋基半导体光催化材料,其具有[BiO]_(2)^(+2)和CO_(3)^(2-)层交替组成的独特层状晶体结构。通过改性可促进(BiO)_(2)CO_(3)的可见光响应能力以及光生电荷分离效率,从而提升其光催化性能。本文主要从贵金属沉积、元素掺杂、异质结构建以及氧空位缺陷等方面综述了碳酸氧铋基光催化材料的改性研究进展。同时指出碳酸氧铋的改性研究需致力于进一步简化制备工艺,并使得改性工艺控制更加精准,以使其在有机污染物降解、光解水制氢等方面得到更好的应用前景。
Bismuth oxycarbonate is a typical bismuth-based semiconductor photocatalytic material with a unique layered crystal structure consisting of alternating[BiO]_(2)^(+2)and CO_(3)^(2-)layers.The visible light responsiveness and photogenerated charge separation efficiency of(BiO)_(2)CO_(3)can be promoted by modification,thus enhancing its photocatalytic performance.In this paper,the research progress on the modification of bismuth oxycarbonate-based photocatalytic materials is reviewed mainly from the aspects of noble metal deposition,elemental doping,heterostructure construction and oxygen vacancy defects.At the same time,it is pointed out that the research on the modification of bismuth oxycarbonate should be devoted to further simplify the preparation process and make the modification process control more accurate,so as to make it get better application prospects in the degradation of organic pollutants,photolysis of water for hydrogen production and so on.
