摘要：Ti02 nanoparticles doped with different amount of lanthanum were obtained by sol-gel approach and followed annealing at different temperature. The crystal size of Ti02 doped with lanthanum was smaller than that of pure Ti02. Photocatalytic activity of Ti02 doped with lanthanum for water splitting into H2 was investigated. The photocatalytic activity of Ti02 doped with lanthanum for water splitting int oH2 is higher than that of pure TiC2. It was found that the optimal photocatalyst was Ti02 doped with 2 wt% lanthanum and calcined at 600 C for 4 h which had hydrogen generation rate 700.6 μ mol h-1.
