| 摘 要： | 以胶原纤维为模板合成了介孔TiO2-Al2O3二元复合氧化物纤维,并利用扫描电镜(SEM)、X射线衍射仪(XRD)、比表面孔隙分析仪、X光电子能谱(XPS)对该二元复合氧化物纤维进行了表征。结果表明所合成的介孔TiO2-Al2O3二元复合氧化物呈纤维状,较好地保留了胶原纤维的结构。当Ti/Al摩尔比为4.88:1时,TiO2-Al2O3二元复合氧化物纤维的平均孔径为7.4 nm,比表面积可达131.0 cm2/g,其中TiO2主要以锐钛矿相存在,Al2O3则以无定形态分散于TiO2晶体间。

| Abstract: | Mesoporous TiO2 -Al2O3 binary composite oxide fiber was synthesized using collagen fiber as the template, and it was characterized using scanning electron microscope （SEM）, X ray diffraction （XRD）, surface area and porosity analyzer （BET） and X -ray photoelectron spectroscopy （XPS）. It can be observed that the me- soporous TiO2 - Al2O3 is in fibrous state, and the structure of collagen fiber is well preserved. When the Ti/AI molar ratio is 4.89 ： 1, the average pore diameter of TiO2 - Al2O3 binary composite oxide fiber is 7.4 nm and its surface area is 131.0 cm^2/g. In addition, it is found that the TiO2 is in anatase phase, while the Al2O3 is in amorphous phase and is dispersed among the TiO2 crystals . |
