A novel Ag/BiOBr composite catalyst has been synthesized by a solution combination with photodeposited method. The as-synthesized catalysts were characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, X-ray photoelectron spectroscopy, and UV-Vis diffuse reflectance spectra. The photocatalytic reaction tests in the degradation of the dyes of acid orange II, rhodamine B and methyl orange showed that the deposition of optimal amount of 1-2 wt% Ag could bring about a big increase in the activity under visible light irradiation. The high photocatalytic performance could be attributed to the strong visible light absorption and low recombination rate of the e -/h ? pairs resulted in by the presence of metal silver nanoparticles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
