The composites BiFeO3/g-C3N4 and BiTiO3/g-C3N4 prepared by sonication have shown higher photo-catalytic degradation of RhB dye by varying parameters such as initial concentration, pH of solution, agitation time and catalyst dose under solar light. The X-ray diffraction pattern showed retention of g-C3N4 structure after modification. The Fourier Transform IR spectra showed efficient attachment of perovskite with g-C3N4 and FESEM image shows the surface morphology of the samples. The BiFeO3/g-C3N4 and BiTiO3/g-C3N4 composites exhibited highest photo-degradation of 99. % for RhB dye in a short span of 35min., 20 min at pH~3 than the pristine BiFeO3 and BiTiO3/g-C3N4 . The kinetics of the photocatalytic degradation for RhB followed a pseudo-first order rate for varying concentration and dose. Both BiFeO3/g-C3N4 and BiTiO3/g-C3N4 are prominent catalysts for ultra-fast degradation of toxic dyes by using solar radiation Keyphrases: Photodegradation, g-C3N4, toxic dye
