In this study, BiFeO3 nanoparticles (BFO NPs) were successfully synthesized by solution combustion method. The effect of different molar ratios of fuel-to-oxidant (F/O = 0.3, 0.555, 0.8) on the phase composition of the nanoparticles was investigated by powder X-ray diffraction. The band gap was calculated about 2.14 eV. The photocatalytic, Fenton and photo-Fenton performances of the catalyst were investigated by degrading tetracycline (TC) and Methyl Orange (MO) using visible light source. The photo-Fenton performance of the NPs reflects much higher than the photocatalytic or Fenton performances. The photo-Fenton mechanism of the BFO NPs and the effect of pH on photocatalytic performance of BFO NPs are also discussed.
