硫化镉插层制备K2La2Ti3-xCexO10

复合催化剂及其活性研究

Abstract

Abstract: The Ce-doped-K2La2Ti3O10（K2La2Ti3-xCexO10） was prepared via a stearic acid method，and CdS-intercalated K2La2Ti3-xCexO10 photocatalysts were prepared by microwave irradiation and water bath method，respectively.The crystal shape，particle size，and morphology of the samples were characterized by X-ray diffractometer（XRD），electronic scanning electron microscopy （SEM），and UV-visible spectroscopy instrument （UV-vis）.The photocatalytic properties of these cata- lysts for degradation of organics were also investigated.Results showed that，the intercalation of CdS expanded the absorption range to visible light，and the photocatalytic activity was enhanced.The photocatalytic activity of microwave-assisted CdS-K2La2Ti3-xCexO10 for the degradation of Rhodamine B was 33.66%，whereas the degradation of water bath prepared ones was 17.68%.
