Effect of Fe3 -doping on Photocatalytic Activing of TiO2 Thin Film for Degradation of Phenol

The transition metal ion-doped TiO_2 filmare prepared with Sol-Gel method, and the effects of doping different metal ions on the ability of TiO_(2)in photocatalyzing degradation of phenol are studied. The results show that doping of Fe~(3+)in TiO_2nanoparticles made photocatalytic efficiency increase, the effects of concentration of doped ions on photocatalytic performance are discussed.     

Ag掺杂Ti02催化降解活性印染废水

以钛酸四丁酯、硝酸银为原料,采用溶胶-凝胶（sol-gel）法制备了掺杂不同含量银的TiO。纳米粉体,并将其应用于活性染料一活性红195、活性黄145及活性蓝19的印染废水的光催化降解。结果表明：适量的银掺杂可有效提高TiOz对活性染料光催化降解活性;当pH值为6～8、银掺杂量为0．6％（Ag／TiOz摩尔比）、活化温度为500~C、催化剂用量为0．1g／L时,光催化降解效率最高,分别为92．5％（活性红195）、90．8％（活性黄145）、83．6％（活性蓝19）。
