摘要

采用改进的Hummers法制备氧化石墨烯，以Bi（NO3）3·5H2O、KCl、Na2WO4为原料，采用微波蚀刻法在其基础上负载BiOCl/Bi2WO6。通过X射线衍射（XRD）、扫描电镜（SEM）、比表面积测定仪（BET）、紫外-可见漫反射（UV-Vis）及透射电镜（TEM）等对所制备的催化剂进行表征。以RhB作为目标降解物，考察其光催化性能。结果表明，当RGO：RGO-BiOCl（质量比）为2%、Bi2WO6：RGO-BiOCl/Bi2WO6（摩尔比）为50%，降解率可达94.6%，远高于纯BiOCl。

Abstract

The oxidized graphite was prepared by modified Hummers method for oxidation treatment of natural graphite. BiOCl/Bi2WO6 catalyst was loaded on RGO by microwave and chemical etching with Bi(NO3)3·5H2O

KCl and Na2WO4. The morphology and structure of as-synthesized products were characterized by X-ray powder diffraction (XRD)

scanning electron microscope (SEM)

Brunauer-Emmett-Teller (BET)

UV-visible diffuse reflectance spectra (UV-Vis DRS) and transmission electron microscope(TEM). Rhodamine B solution was used as target degradation to investigate the photocatalytic performance of catalyst. The results illustrated that RGO:RGO-BiOCl(mass ratio) was 2%

Bi2WO6:RGO-BiOCl/Bi2WO6 (molar ratio) was 50%

and the degradation rate reached as high as 94.6%

compared to pure BiOCl.
