摘　　要：以Ti25Zr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)2·6H2O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BaTi0.75Zr0.25O3纳米管,并且纳米管的结晶性良好;优化出水热法制备BaTi0.75Zr0.25O3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）03 nanotubes were fabricated by hydrothermal method using Ti-Zr-O nanotube template which obtained via anodization of Ti25Zr substrate and Ba（OH）e solution. The effect of Ba（OH）2 6H2 O 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 BaTi0.75Zr0.25O3 nanotubes with the diameter of （70 ± 5）nm and the length of 6μm were prepared suc- cessfully. The optimal process parameters for preparing BaTi0.75Zr0. 25O3 nanotubes are shown as follows： the concentration of Ba（OH）2 6H2O was 0.08mol/L and the hydrothermal temperature was 150℃.
