Preparation and Photocatalytic Property of Lanthanum-doped TiO2 Nanoparticles

摘要：

　　Nano-TiO2 photocatalyst powders were prepared through the sol-gel method and supercritical fluid drying(SCFD).The TG-DTA,XRD,particle size distribution technique,SEM were used to characterize the hyperfine TiO2 particles.The lanthanum-doped TiO2 with different mass percentage of La3+ were compared with pure TiO2 when used as photocatalyst in degradation of methyl orange.The best catalytic activity was observed with 0.02(mol)%La-TiO2.Photocatalytic efficiency of the 0.02(mol)%La-TiO2 is improved by 30.79% comparing to pure TiO2.
