摘要
水热法合成TiO2纳米管,以Fe(NO3)3为前驱体制备Fe3+掺杂TiO2纳米管(Fe2O3/TiO2),并系统研究其光催化降解染料废水活性。结果表明,Fe3+掺杂能有效提高TiO2纳米管光催化降解染料废水效果,其中Fe2O3掺杂量为4%(ω)时,其光催化性能最好,最高降解率可达99%,且具有较好的稳定性。研究证实,Fe2O3/TiO2复合材料具有良好的光催化降解亚甲基蓝染料废水性能。
The hydrothermal prepared TiO2 nanotubes, Fe2O3/TiO2 composites and their photocatalytic properties were investigated. The results showed that Fe3＋ doping can enhance the photocatalytic propertie efficiently. When the content of Fe2O3 was optimized to 4% （ω）, the highest catalytic ability （conversion 99% ） and good stability were obtained. The Fe2O3/TiO2 composites had good photoeatalytic ability for themethlene blue dye wastewater.
