Abstract
This work reports synthesis and characterization of mono and bimetal doped TiO2-based photocatalyts using Bi and Fe metals prepared via wet impregnation method. Photocatalytic performances of the synthesized catalysts were tested for the degradation of methylene blue. Results revealed that 1%Bi/TiO2 (w/w) exhibited best photocatalytic performance and achieved 80% degradation of 50 ppm MB solution within two hours. The monometallic doping showed better performance than the bimetallic doping of Bi and Fe. This diminished performance with co-doping was due to the agglomeration effect which accelerates recombination of electrons and holes. First order-kinetic model was used for the study of degradation.
