The RGO@ZnO composite nanomaterial has unique structural features including well-dispersed NPs on the surface and dense NPs loading. This composite exhibited a greatly improved Rhodamine B (RhB) adsorption capacity and an improved photocatalytic activity for degrading RhB compared to neat ZnO NPs. These properties made RGO@ZnO reusable for pollutant adsorbent. The composite showed an excellent cycling performance for organic pollutant removal up to 99% recovery over several cycles via simulated sunlight irradiation.Keywords: Adsorption capacities; Cycling performance; grapheme; In-situ; Nanomaterial; Photo-reduction; Photocatalytic activities; Photoreduction method; Pollutant management; Pollutant removal; Reduced graphene oxides; Rhodamine B; Simulated sunlight; Structural f grapheme; photocatalytic activity; photoreduction; pollutant removal; recovery201210.1021/am300445f2016-02-24
