Abstract

Nanoscale BaFe12O19/ Sm2Ti2O7 and BaFe12O19/ Sm2Ti2O7/Ag ternary nano-hybrid were successfully synthesized by a new method for the first time. PEG, PVA, and PVP were used to investigate their effects on the morphology and particle size of final products. The photocatalytic efficiency of BaFe12O19/ Sm2Ti2O7/15%Ag was improved by 59% which was higher than pure BaFe12O19/ Sm2Ti2O7 for the degradation of MB. In this work, Ag was doped with BaFe12O19/ Sm2Ti2O7 with the aid of improving its photocatalytic activity and stability toward degradation of dyes under visible light irradiation. Transmission electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy, Fourier transform infrared, photoluminescence, diffuse reflection spectroscopy, and Field emission scanning electron microscopy were applied to characterize BaFe12O19/ Sm2Ti2O7/Ag ternary nano-hybrid.
