以Ti25 Zr合金阳极氧化获得的 Ti-Zr-O 纳米管为模板,采用 Ba(OH)2通过水热反应法制备 Ba (ZrTi)O3纳米管,研究了温度、Ba(OH)2·6H2 O 浓度等工艺参数对Ba(ZrTi)O3纳米管微观组织结构和形貌的影响规律。SEM、TEM及XRD和XPS表征研究表明,获得了管径为(70±5)nm,长度为6μm 的Ba-Ti0.75 Zr0.25 O3纳米管,并且纳米管的结晶性良好；优化出水热法制备 BaTi0.75 Zr0.25 O3纳米管的最佳合成温度为150℃,Ba(OH)2·6H2O 的浓度为0.08mol/L。
Ba(ZrTi)O3 nanotubes were fabricated by hydrothermal method using Ti-Zr-O nanotube template which obtained via anodization of Ti25Zr substrate and Ba(OH)2 solution.The effect of Ba(OH)2·6H2O con-centrations and hydrothermal temperatures on the microstructure of Ba(ZrTi)O3 nanotubes were investigated. The structural characteristics and surface morphology were examined by X-ray diffraction,X-ray photoelectron spectroscopy,scanning electron microscopy,and transmission electron microscopy,respectively.The results show that BaTi0.75 Zr0.25 O3 nanotubes with the diameter of (70±5)nm and the length of 6μm were prepared suc-cessfully.The optimal process parameters for preparing BaTi0.75 Zr0.25 O3 nanotubes are shown as follows:the concentration of Ba(OH)2·6H2O was 0.08mol/L and the hydrothermal temperature was 150℃.
