Abstract: One-step hydrothermal synthesis was used to prepare spherical Bi2WO6 and Ag/Bi2WO6 photocatalysts, and the properties of the samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscope (FESEM), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS), ultravioletvisible spectrophotometry (UV-Vis) and other means. Under the condition of simulating sunlight, the catalytic activity and mechanism of Bi2WO6 and Ag/Bi2WO6 were studied using methyl orange (MO) as degradation product. The results show that compared with Bi2WO6, Ag/Bi2WO6 has a better degradation effect on MO under the same conditions. When the Ag doping amount was 1%(n/n), the degradation rate (180 min) reached 91.4%, and the degradation rate of the recovered sample was also obtained, which also reached 81%. In addition, a preliminary study of the degradation mechanism of Ag/Bi2WO6 composites was also performed. |
