Studies on Photocatalytic Activity of Perovskite Type LaFe1-x CuxO3

Abstract

Abstract: LaFeO₃ and a series of Cu-doped compounds LaFe_1-x Cu_xO₃ were prepared by citrate method. The photodegradation experiments of various water soluble dyes were carried out in the suspension of LaFe_1-x Cu_xO₃ acting as the photocatalysts. The photocatalytic activity of LaFeO₃ and LaFe_1-x Cu_xO₃ was studied with IR, UV-Vis, and photoacoustic spectroscopy. The influence of doping on photocatalytic activity was also analyzed by PATand XPStechnology. The results show that the doping can greatly improve the photocatalytic activity of LaFeO₃.

Key words: LaFe_1-x Cu_xO₃, Photocatalytic activity, Doping
