纳米 TiO2颗粒的水解制备及其光催化性能研究
Hydrolysis preparation of TiO 2 nanomaterials and its photocatalytic performance
摘要
Abstract
Different TiO2 nanostructures are prepared by hydrolyzed the tetrabutyl titanate in HCl , CH3 COOH , NH3 ・ H2 O and NaOH solutions , respectively , and then annealed at 500 ℃ in air . The structure of samples are tested by scanning electron microscopy ( SEM ) , high‐resolution transmission electron microscopy(HR‐TEM ) ,X‐ray diffraction pattern (XRD)and Raman spectra . Their phohocatalytic performance are tested by photo‐degradation of Rhodamine B ( RhB ) dye . The concentration of Rhodamine B molecule is measured by UV spectrophotometer . The results show that the obtained sample are anatase TiO 2 nanostructures . The morphology of the samples are different for different hydrolysis solution .Because of its excellent surface sturcture , the TiO2 nanomaterial prepared in CH3 COOH solution has good photocatalytic performance .关键词
