摘要

通过调控单斜相钒酸铋(mBiVO4)的微观结构,以便改善光生电荷特性,从而提高其光催化活性。mBiVO4材料的纳米结构能够加快电子迁移速率从而提高光生电荷的分离效率;特殊的形貌能够缩短光生电荷迁移路径而有利于光生电荷快速分离至表面,进而促进表面活性位点的催化反应。阐述了近年来诸如花生状、橄榄状、花状、支状和其他形状等不同形貌的三维(3D)纳米结构mBiVO4光催化材料在光催化领域的研究进展,并对这类光催化材料未来的发展趋势进行了展望。

Abstract

The characteristics of photogenerated charge can be improved by regulating the microstructure of monoclinic bismuth vanadate (mBiVO4),and consequently enhanced its photocatalytic activity.The nanostructure of mBiVO4 material can be able to accelerate the electron migration rate as well as promoted the separation efficiency of photogenerated charge.The special morphology can shorten the migration path of photogenerated charge which was advantageous to the separation of photogenerated charge to the surface,and then facilitated the photocatalytic reaction of surface active sites.The research process of the three-dimensional (3D) nanostructured mBiVO4 photocatalytic materials with different morphologies,such as peanut-like,olive-like,flower-like,dendrite,and other shapes in the field of photocatalytsis were described,and looked forward to the future development of this kind of photocatalysis material.
