摘　　要：以钛酸丁酯为原料,用溶胶-凝胶(So l-gel)法制备了掺杂锡离子的纳米T iO 2粉末。采用透射电子显微镜和X光衍射仪对粉体的粒径、物相、形貌和热稳定性进行了表征。通过粉体对苯酚的降解情况对其光催化活性进行了测试,结果表明5%Sn4+-T iO 2具有良好的光催化氧化性能。Nanometer Sn^4＋- doped TiO2 powder was obtained in microemulsion of CTAB/C4H10O/ C6H12/H2O with TiCI4. The size,structure, appearance and thermostable properties were analyzed by TEM and XRD. The photocatalytic oxidation properties were examined by the degradation of phenol. The resuits indicate that the photocatalytic oxidation properties of 5%Sn^4＋ -TiO2 were appropriate.
