摘　　要：钒酸铋(BiVO_(4))光催化剂具有禁带宽度窄、太阳能利用率高等优势受到广泛关注。然而BiVO_(4)同时也存在光载流子容易复合、吸附有机污染物能力有限、粉体材料分离困难等问题,影响了其在环境领域的实际推广应用。而金属氧化物负载改性BiVO_(4)可以促成p-n异质结结构,进而提高BiVO_(4)光载流子分离效率,同时可以有效改变BiVO_(4)微观形貌、增加反应活性点位。另外金属氧化物的负载掺杂还赋予了该材料磁分离特性,因此金属氧化物负载改性BiVO_(4)成为其推广应用的一种可能。Bismuth vanadate(BiVO_(4)) photocatalyst has attracted extensive attention because of its narrow band gap and high solar energy utilization.However, BiVO_(4)also has some problems, such as easy recombination of optical carriers, limited ability to adsorb organic pollutants and difficult separation of powder materials, which affect its practical application in the field of environment.The metal oxide loading modification of BiVO_(4)can promote the p-n heterojunction structure, improve the efficiency of BiVO_(4)optical carrier separation, effectively change the micro morphology of BiVO_(4)and increase the active sites of the reaction.In addition, the loading doping of metal oxide also gives the material magnetic separation characteristics, so the loading modification of BiVO_(4)by metal oxide has become a possibility for its popularization and application.
