WO3/g-C3 N4复合催化剂的制备及其可见光光催化性能分析
Synthesis and visible-light photocatalytic activity of WO3/g-C3 N4 composite photocatalysts
摘要
Abstract
The WO3/g-C3 N4 composite visible photocatalysts were successfully synthesized by an ultrasound-microwave-protonation process using HCl solution as solvent.The prepared samples were characterized by X-ray diffraction (XRD),scanning electron microscopy (SEM),transmission electron microscopy (TEM),ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS)and Brunauer-Emmett-Teller (BET )specific surface area and photogradation of Rhodamine B (RhB )for visible-light properties.This results show that the composite catalysts are composed of WO3 nanosheets loading on g-C3 N4 nanoplates.When the mass fraction of WO3 is 40%,the sample prepared by heating the precursor at 500 ℃ for 2 h has better photocatalytic activity than that prepared by pure WO3 and g-C3 N4 .The WO3/g-C3 N4 can photodegradate 98% 100 mL RhB solution with concentration of 10-5 mol/L after 5 h visible-light (wavelength is larger than 420 nm)irradiation.关键词
