Reduced graphene oxide, zinc sulfide, rhodamine B, photocatalysis, compositesAbstract
In this work the obtaining of ZnS-rGO composites is reported by precipitation of zinc sulfide particles within previously obtained aqueous dispersions of reduced graphene oxide. ZnS particles and ZnS-rGO composites were characterized by X-ray diffraction, Uv-Vis spectroscopy, scanning electron microscopy, and surface area analysis. The photocatalytic activity of the composite was analyzed by degrading aqueous solutions of rodamine B radiating with Xenon light. It was observed a decrease on the reaction half-life time of the organic pollutant from 270 to 147min, compared to the particles of neat ZnS.
