RGO/ZnO composites with different size of ZnO particles have been fabricated via a one-step facile solvothermal method. The photocatalytic activities of these composites have been investigated toward dye degradation and Cr (IV) reduction in an aqueous phase. It is found that ZnO-S1, with relatively...
