CNT-CdS-TiO2光催化剂的制备及其光催化性能
Preparation and Photocatalytic Properties of CNT-CdS-TiO2
摘要
Abstract
The TiO2,CdS-TiO2,CNT-CdS-TiO2 photocatalysts were prepared by sol-gel method with cadmium nitrate as Cd source material,tetrabutyl titanate as Ti source,thiourea as S source and CNT as support.The structure and morpholoy of TiO2,CdS-TiO2 and CNT-CdS-TiO2 were investigated by X-ray diffraction (XRD),scanning electron microscopy (SEM) technique and transmission electron microscopy (TEM).The result shows that TiO2 is anatase phase and CdS is hexagonal phase.TiO2 and CdS cover on the surface of the CNT uniformly.UV-visible spectra and photocatalytic performance of TiO2,CdS-TiO2 and CNT-CdS-TiO2 were tested.Testing for UV-visible absorption spectroscopy indicates that the absorption peaks for CdS-TiO2 and CNT-CdS-TiO2 red shifted.Photocatalytic degradation of methylene blue shows that CdS-TiO2 and CNT-CdS-TiO2 shows higher catalytic activity than pure TiO2 under the irradiation of visible light.The degradation of methylene blue for CNT-CdS-TiO2 has reached 55％.关键词
