The Preparation of BiOCl Microspheres and its Photocatalytic Performance

Abstract

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.
