摘　　要：以硫酸钛为原料,用水热法制备了掺Fe3+的TiO2粉末,并对其晶相结构进行了分析,考察了自制掺Fe3+的TiO2对甲基蓝溶液的光催化性能。结果表明:所制备的TiO2为锐钛矿型TiO2(A-TiO2)。可见光照下,用自制掺Fe3+的A-TiO2降解甲基蓝溶液的最佳条件是:于ρ(甲基蓝)为8mg/L的溶液中加入0.0203g掺Fe3+为5%(摩尔分数)的A-TiO2粉末,并加入φ(H2O2)为4%,室温反应4h,最高降解率达到约88%。Fe3+-doped TiO2 powders were prepared by hydrothermal method using titanium sulfate as raw materials.Phase structure of prepared powders was analyzed.Photocatalysis properties of the powders were also investigated.The results show that as-prepared Fe3+-TiO2 crystals are anatase TiO2(A-TiO2),and the highest degradation rate of methyl blue is about 88% under following optimum conditions:adding 0.020 3 g as-prepared 5% Fe3+-doped(mole fraction) A-TiO2 powders and φ(H2O2) is 4% into the ρ(methyl blue) of 8 mg/L...
