Preparation and Photocatalytic Performance of Novel Zn-doped C/Nb2O5 Nanoparticles Catalyst†

doi:10.7503/cjcu20170346

Abstract

Abstract:

Novel Zn-doped C/Nb₂O₅ nanoparticles were prepared via a simple hydrothermal method. The nanoparticles were characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM) and X-ray photoelectron spectroscopy(XPS). The as-prepared nanoparticles presented enhanced crystallinity with ultrafine morphology and Zn element was confirmed to exit as the form of ZnO randomly on the surface of C/Nb₂O₅. The amount of surface oxygen vacancies(SOVs) on the catalyst surface reached an optimal value when the molar ratio of Zn/Nb was 10% proved by the XPS and surface photovoltage spectroscopy(SPS) results. The catalyst with an optimal doping amount of Zn exhibited much higher photocatalytic activity than P25 and commercial Nb₂O₅ towards degradation of Rhodamine B(RhB) and Rhodamine 6G(Rh6G) under visible light irradiation.

Key words: C/Nb2O5, ZnO, Surface oxygen vacancies(SOVs), Photocatalytic activity, Rhodamine B(RhB), Rhodamine 6G(Rh6G)
