AgBr/AgBrO3 nanoparticles loaded on porous carbon were prepared by an impregnation method and they were further transformed into Ag/AgBr hybrid during the photocatalytic degradation process. X-ray diffraction pattern, transmission electron microscope and UV-vis diffuse reflectance spectroscopy were applied to investigate the structures, morphologies and optical properties of as-prepared samples. The surface plasmon resonance (SPR) absorption of metallic Ag was observed from UV-vis diffuse reflectance spectroscopy. The photocatalytic activities were evaluated by the photodegradation of Rhodamine B under visible light irradiation. (C) 2017 Elsevier B. V. All rights reserved.
