Photocatalytic Degradation of Deactive Deep Blue in the Presence of LaFeO3 and La0.95Cao.o5FeO3 Prepared by a Stearic Acid Gel Method

摘要

Photocatalysed degradation of a textile dye derivative,reactive deep blue,was investigated in aqueous suspensions of LaFeO3 and Lao.95Ca0.05FeO3 under a variety of conditions.The effects of various parameters such as the amount of catalyst,initial substrate concentration,the amount of Ca-doped have been determined.Compared to LaFeO3,Lao.95Cao.05Fe)3 was much higher in catalytic ability.The photocatalytic degradation of reactive dyes was different with the different amount of Ca-doped.
