| 摘 要： | 采用溶胶-凝胶法制备了N、Fe双掺杂的纳米TiO2光催化材料.借助XRD、XPS对制备的光催化材料进行表征,并通过晶粒尺寸、晶粒比表面积和晶格畸变率等的分析,研究了N、Fe双掺杂对TiO2性能的影响.研究结果表明,N、Fe双掺杂抑制了TiO2由锐钛矿向金红石的转变,明显延缓了TiO2相的转移;N、Fe双掺杂可明显减小晶...

| Abstract: | A nanosized TiO2 photocatalyst co-doped with N,Fe was synthesized by the sol-gel method.The prepared samples were characterized by XRD and XPS.The grain size,grain surface area and lattice distortion for the samples were analyzed and the effect of N,Fe co-doped in TiO2 was studied.The results showed that the change from anatase to rutile transformation with temperature was inhibited by N,Fe co-doped and the phase transfer of TiO2 was significantly delayed.By N and Fe co-doping,the grain size was clearly red... |
