| 摘 要： | 利用X射线衍射、拉曼光谱、紫外-可见漫反射光谱和X射线光电子能谱研究了铁和铈对TiO2的共掺杂．当利用溶胶-凝胶法进行单独掺杂时,铁离子可以进入锐钛矿TiO2骨架,但铈离子却不能进入TiO2骨架;当铁和铈共掺杂时,铁离子和铈离子可以同时进入TiO2骨架．铁-铈共掺杂的TiO2表面羟基浓度要远高于单独掺杂或者纯的TiO2．第一次观察到过渡金属离子共掺杂进入TiO2骨架的协同效应．

| Abstract: | The co-doping of iron and cerium into TiO2 was studied by means of X-ray diffraction, Raman spectroscopy, UV-Vis diffuse reflectance spectroscopy and X-ray photoelectron spectroscopy. when separately doping via the sol-gel method, iron was introduced in the framework of anatase TiO2 whereas cerium was not; interestingly, both iron and cerium were introduced in the framework when co-doping by the sol-gel method. The co-doped TiO2 behaves much more intense surface hydroxyl concentration than the separately-doped and pure TiO2. This observation demonstrates for the first time a cooperative effect in the co-doping of transitional metals in the framework of TiO2. |
