The Bi2WO6 catalyst was prepared by hydrothermal method using Bi(NO3)3•5H2O and Na2WO4•2H2O. The synthesized catalyst was characterized in detail by X-ray power diffraction (XRD), Scanning electron microscopy (SEM), UV-Visible diffuse reflectance spectra (UV-vis DRS) and N2 adsorption-desorption isothermal curves (BET). The result indicated thatthe Bi2WO6 catalyst was a nanometer-sized cross-stacked microsphere with a mesoporous structure, particle size of about 6um, specific surface area of 12.01 m3/g. Under visible-light irradiation, The catalytic effect of Bi2WO6 catalyst on the oxidation of benzyl alcohol to benzaldehyde was tested. The results showed that, isopropanol as the solvent and 0.8 mmol of NaOH as the alkali source, the Bi2WO6 catalyst had exhibited excellent catalytic activity for the benzaldehyde production by catalytic oxidation of benzyl alcohol, and the yield of benzaldehyde could reached 80.8%. © 2020, Editorial Office of Speciality Petrochemicals.
