The LaFeO3 nanoparticle was synthesized using Fe(NO3)3 and La(NO3)3 as starting materials by homogeneous precipitation method. The as-prepared LaFeO3 product was characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (DRS). XRD and SEM demonstrate the successful synthesis of single phase perovskite LaFeO3 and with 60-80 nm particle size. It was found that the as-prepared LaFeO3 shows strong visible-light absorption with absorption onset of 532 nm, indicating a narrow optical band gap of 2.33 eV. Furthermore, the as-prepared LaFeO3 shows high visible-light photocatalytic activity for decomposition of methylene blue in comparison with the commercial Degussa P25.

Novel non-porous Ag3PO4/AlPO4 composites with a stick shape were synthesized using the homogeneous precipitation method and characterized by XRD, FESEM, XPS, UV-vis spectroscopy and BET method. The photocatalytic performance was evaluated by degradation of MB and MO upon irradiation with visible light. Results indicate that when the molar ratios of Ag3PO4 to AlPO4 are 6:4 or higher, remarkable increases in photocatalytic activity were observed compared with the pure Ag3PO4 powder. The possible mechanism of photocatalytic degradation of dyes by Ag3PO4/AlPO4 composites was proposed.
