The Bi2Ti4O11 nanorods were obtained by a one-step alcohol-thermal method. The sample was synthesized at 100°C and calcined at 600°C, using Bi(NO3)3•5H2O, TiCl4 and absolute ethanol as reactants. It then characterized by XRD, SEM and UV-vis DRS. The results showed that the sample was nanorod with diameter about 30nm and length about 200nm. The photocatalytic experiment represented that the photocatalyst could effectively degrade more than 99% Rhodamine B( RhB) within 85 min under irradiating of visible light.

The BiOCl microspheres photocatalyst was obtained by a one-step alcohol-heating method. The reactants were Bi(NO3)3•5H2O、TiCl3 and absolute ethanol, and the sample was synthesized at 100°C and calcined at 600°C. It then characterized by XRD, SEM, UV-vis DRS. The results showed that the sample was microspheres, having excellent photocatalytic activity that the sample could degradate more than 94% of RhB in 65 minites which is better than P25 under UV irradiation.
