In this study, LaFeO3 photocatalysts were synthesized by using co-precipitation method at different calcination temperatures of 600 °C, 700 °C, and 800 °C. Graphene was also introduced into LaFeO3 to improve the photocatalytic performance. The photocatalysts were characterized by using X-Ray Diffraction (XRD), Brunauer-Emmet-Teller (BET) surface area analysis, and Fourier Transform Infrared (FTIR) spectroscopy. The prepared photocatalysts were also evaluated to determine their photocatalytic degradation activities against methylene blue (MB) under visible light irradiation. LaFeO3 with the calcination temperature of 800 °C with graphene supported showed orthorhombic structure and the highest photocatalytic performance. The different structure might affect the photocatalytic performance of samples, while the role of graphene on the nanocomposite could act as an electron transport layer and inhibited the recombination of photogenerated electron-hole pairs. The stability of the catalyst on the photocatalytic process was also studied.
