摘要
通过共沉淀法制备了掺铁纳米TiO2粒子,并用掺铁后的纳米TiO2粒子作为催化剂,对气相甲苯进行光催化降解实验。利用色谱、质谱、红外等测试方法研究了掺铁浓度对TiO2光催化性能的影响,同时探讨了光催化降解甲苯的机理。
Fe-doped nanometer TiO2 was prepared by coprecipitation method and used as catalyst in photocatalysis degradation test at gaseous foluene. The influence of Fe-doped concentration to TiO2 photocatalysis property by chromatogram, mass spectra and infra-red etc monitoring methods was studied and mechanism of photocatalysis degradation of toluene was discussed.
