摘要

构建复合光催化材料不仅能够拓展单一光催化材料的光谱响应范围

而且能够提高光生载流子的分离效率.为了进一步提高BiOCl在可见光下的光催化性能

本文利用BiOCl与Bi_2S3溶度积常数的差异

将Na_2S溶液加入到BiOCl纳米片悬浮液中

通过水热反应制备了Bi_2S3/BiOCl复合光催化材料.探讨分析了Na_2S浓度对所得复合材料光催化还原六价铬[Cr(Ⅵ)]性能的影响.研究结果表明:Bi_2S3/BiOCl复合材料具有较强的可见光吸收能力和较高的光生载流子分离效率

当Na_2S的浓度为0.016 mol/L时所得复合材料具有最佳的光催化性能.

Abstract

The construction of composite photocatalyst can not only expand the light absorption range

but also improve the separation efficiency of photogenerated carriers.In order to improve the photocatalytic performance of BiOCl under visible light

the difference in solubility product constants between BiOCl and Bi_2S3 was employed in this paper

and the Bi_2S3/BiOCl composite was prepared by adding Na2 S solutionto BiOCl nanosheets suspension under hydrothermal condition.The influence of Na2 S concentration on the photocatalytic reduction of hexavalent chromium [Cr(Ⅵ)] of the obtained composite was investigated and analyzed. The results show that the as-synthesized Bi_2S3/BiOCl composite has strong visible light absorption performance and enhanced photocarrier separation efficiency

and the sample prepared with 0.016 mol/L Na2 S exhibits the highest photocatalytic performance.
