Abstract

BiOBr composites with heteropolyacids (H3PW12O40, PTA) were encapsulated within a zeolite using the impregnation method. The samples were characterized by Fourier transform infrared spectrophotometry (FT-IR), X-ray diffractometry (XRD), scanning electron microscopy (SEM), UV-vis diffuse reflectance spectra, and N2 physisorption, and their photocatalytic activity was investigated by photocatalytic degradation of methyl orange, whose results indicate that zeolite (SBA-15)-modified BiOBr composites with immobilized phosphotungstic acid exhibit excellent photocatalytic properties.
