采用电化学阳极氧化法在含氟溶液中制得结构规则、有序核-壳结构的TiO2纳米管,再以上述TiO2纳米管为基质,在一定条件下水热合成制得TiO2/ZnO纳米复合材料,对所制备的纳米复合材料进行表征。在阳极氧化电压为60 V、反应时间9 h、溶液pH=6时制得的TiO2纳米管形貌最佳,当锌浓度为0.2 mmol/L时制得TiO2/ZnO纳米复合材料的包覆明显且清晰;同等条件下采用SDS制得的纳米材料尺寸比用CTAB的小。 TiO 2 nanotubes with structured and ordered core-shell structure were prepared by electrochemical anodic oxidation in a fluorine-containing solution. Then, the above TiO 2 nanotubes were used as substrates to synthesize TiO2 / ZnO nanocomposites under hydrothermal conditions The prepared nanocomposites were characterized. The morphology of TiO2 nanotubes prepared at anodic oxidation voltage of 60 V, reaction time of 9 h and solution pH = 6 was the best. When the zinc concentration was 0.2 mmol / L, the coating of TiO2 / ZnO nanocomposite was obvious And clear; under the same conditions using SDS prepared nanomaterials smaller size than CTAB.
