Sol-Gel Template Synthesis and Photocatalytic Property of Nano-TiO2 Co-doped with La and Fe

摘要：

　　Nano-TiO2 co-doped with lanthanum and iron photocatalyst powders were prepared with the sol-gel method and supercritical fluid drying(SCFD).The XRD,particle size distribution technique,TEM were used to characterize the hyperfine TiO2 particles.The TiO2 co-doped with different mass percentage of La3+ and Fe3+ were compared with pure TiO2 when being used as photocatalyst in degradation of methyl orange.The best catalytic activity was observed by TiO2 co-doped with 0.02%La-0.05%Fe(mol).Photocatalytic efficiency of the TiO2 co-doped with 0.02%La and 0.05%Fe is 1.625 times the pure TiO2.
