摘要
The Gadolinium nitrate was added into the hydrolytic process of tetrabutyl titanate (TBOT) to synthesize the Gd3+/TiO2 composite material with visible response activity by sot-gel technology. Some means, such as TEM, XRD, TG-DTA and UV-Vis were used to character the composite material. The results showed, when the doping amount of Gd3+ was 0.5%, the maximum absorption of composite material appeared in about 550 nm, the Gd3+ might enter into the crystalline lattice of TiO2 and form a new bandwidth (E-g=1.27 eV). The photocatalytic activity of Gd3+/TiO2 composite material was better than that of pure TiO2 particles.
