摘　　要：以钛酸四丁酯为主要原料,硫酸锰溶液为掺杂剂,采用超声分散法制备了含锰的二氧化钛光催化剂。并用X射线衍射(XRD)和透射电镜(TEM)对粉体的结构、粒径大小、物相、形貌等进行了表征。经500℃焙烧2h后,锰掺杂的二氧化钛粉末为锐钛型结构,其平均粒径为13nm,由于在XRD图谱上未发现有新相的生成,因此,可知锰离子是经过焙烧渗入到了二氧化钛的晶格中,掺杂所引起的变化主要是由于锰离子渗入二氧化钛晶格引起的。Mn doped titanium dioxide photoeatalyst was prepared via ultrasonic dispersion method with using tetrabutyl titanate and manganese sulfate solution as main feedstock. The powder structure, particle size, morphology and phase were characterized by X-ray diffraction （XRD） and transmission electron microscope （TEM）. After calcination at 500~C for 2h, Mn doped titanium dioxide powder was kept as anatase phase with the average particle diameter of 13nm. Because the new phase was not found from XRD analysis, the changes were probably induced by the infiltration of manganese ion into titania crystal lattice.
