Synthesis of Bi2WO6/TiO2 Nanocomposites for the Photocatalytic Degradation of Ethylene†

doi:10.7503/cjcu20170601

Abstract

Abstract:

Bi₂WO₆/TiO₂ nanocomposites were synthesized via solvent thermal method and characterized using X-ray powder diffractometer(XRD), scanning electron microscope(SEM), transmission electron microscope(TEM) and Fourier transform infared spectrometer(FTIR). The results show that TiO₂ nanoparticles can be attached to the surface of Bi₂WO₆ through the interaction of surface groups, thus leading to the hetergeneous structure. Moreover, the Bi₂WO₆/TiO₂ nanocomposites have smaller grain size and higher specific surface area compared with single Bi₂WO₆ nanoparticles, which can be contributed to the reinforcement of photocatalytic activity under visible light irradiation. Experiments on degradation of ethylene indicated that Bi₂WO₆/TiO₂ composites exhibited excellent photocatalytic performance under both simulated solar light irradiation and visible light irradiation. The rate constant K' of Bi₂WO₆/TiO₂ could reach up to 9.312×10^-4 min^-1 under visible light irradiation, which increased by 89.34% and 884.25% compared with sole Bi₂WO₆ and TiO₂, respectively.
