ZnO-GO composites, azadirachta indica, graphene oxide, photocatalysis, rhodamine BAbstract
Graphite oxide was synthesized following Hummer's method and through ultrasound exfoliation, graphene oxide, GO, was obtained. The extract in aqueous solution of dried and pulverized leaves of Neem (Azadirachta indica) was mixed with GO as a previous step in obtaining the composites. Aqueous solutions of Zinc Acetate were prepared which were mixed with the solution previously prepared with GO and neem extract, obtaining ZnO-GO. Varying the percentage of GO, the photocatalytic activity of composites was studied through the degradation of Rhodamine B, RhB. The half-life times of RhB were calculated according to the Langmuir-Hinshelwood model.
