The Bi 2O 3 was prepared from Bi(NO 3) 3·5H 2O, followed by calcination of its alkali salt. The Bi 2O 3 was used as photocatalyst in photocatalytic decoloration of dyes. The results showed that the Bi 2O 3 exhibited ...
The perovskite(ABO 3) type oxides have a photocatalytic activity that can be characterized with decolorization of some organic dyes under irradiation of mercury lamp. The experimental results show that the photocataly...
