摘要：

The MWCNT/Bi2WO6 composite photocatalysts with high photocatalytic activity were successfully synthesized from multiwalled carbon nanotubes and Bi2WO6 via hydrothermal method. The structures and morphology of the samples were characterized by XRD, SEM, TEM, XPS, BET and UV-Vis. The photocatalytic performance of the catalyst was investigated by taking Rhodamine B as the target pollutant. The results indicated that the obtained composite presented orthorhombic crystal structure, the MWCNTs alternately attached to the lamella structure of Bi2WO6 to form the composite. The synthesized MWCNT/Bi2WO6 possessed large specific surface area and narrow band gap, which could effectively inhibit the recombination of photogenerated electrons and holes, increase the quantum transfer efficiency and was more likely to be excited by light. The MWCNT/Bi2WO6 photocatalysts exhibited the best catalytic performance with the loading amount of 2%. Under the simulated sunlight test, the photodegradation efficiency of MWCNT/Bi2WO6 to 10 mg/L Rhodamine B could reach as high as 98.8%. © 2019,Materials Review Magazine. All right reserved.
