| 摘 要： | 本文采用静电纺丝法制备了不同Ag负载含量的Ag/BiVO4纳米纤维复合材料,并对其相结构,形貌,可见光催化性能进行了表征。结果表明,Ag的引入能够很大程度的提高复合材料的光催化效率,10%Ag负载的Ag/BiVO4复合纳米纤维能够在可见光辐照20min内将罗丹明B完全降解。这种异质结够有利于光生电子对的分离,提高光生载流子寿命,是Ag/BiVO4复合纳米纤维光催化性能显著提高的原因。

| Abstract: | : A series of Ag loadedAg/BiVO4 composite nanofibers were synthesized through electrospinning and heat treatment process. The phase structure, morphology and photocatalytic performance were tested. The result shows that Ag loading can significantly enhance the photocatalytic activity. RhB can be completely degraded in 20min under visible light irradiation of 10% Ag loading. The heterostructure promoted the charge separation as well as the lifetime of the photo generated electron and holes, resulting in the enhancement of the photocatalytic activity. |
