ZnO/graphene-oxide nanocomposite with remarkably enhanced visible-light-driven photocatalytic performance

► ZnO/graphene-oxide (ZnO/GO) nanocomposite was synthesized via a facile chemical deposition route. ► The ZnO/GO nanocomposite exhibited remarkably enhanced visible-light-driven photocatalytic performance. ► The mechanism for photocatalytic degradation of methylene blue (MB) under visible light was discussed.
