| 摘 要： | 采用柠檬酸溶胶凝胶法制备出复合氧化物LaFeO3,并以其为催化剂,以高压汞灯模拟太阳光,对染料酸性红B进行降解。实验考查了反应时间、催化剂用量、起始浓度对降解率的影响,同时用XRD、TEM等手段对产品进行了表征。研究结果表明:所制备的催化剂LaFeO3为纳米级钙钛矿型复合氧化物,对染料酸性红B有良好的催化降解效果。50mL、10mg/L酸性红B溶液用0.125g催化剂降解70min降解率达到94.5%。

| Abstract: | Perovskite oxides LaFeO3 was prepared by citric acid sol-gel process which was characterized by XRD,TEM testing techniques. Using a luminous Hg lamp as irradiator, the degradation experiments of acid red B were carried out.The influences of reaction time, amount of catalyst, initial concentration of acid red B were investigated.The results show that LaFeO3 exhibited a higher photocatalytic activity. The degradaion rate of acid red B was highed up 94.5%with 0.125g catalyst in 50mL,10mg/L acid red B degrading 70min. |
