Abstract
Two different zinc oxide/reduced graphene oxide (ZnO/RGO) nanocomposites with flower-like and rod-like ZnO particles were facilely controllably synthesized from ammonia, using glucose and sodium citrate as the green reducing agent, respectively, which combined the growth of ZnO particles and the reduction of GO in the one-step hydrothermal process. The results suggest that identical amine source can result in the assembly of different ZnO morphologies, which are decorated on the surfaces and the interlayers of RGO sheets and act as spacers to keep the neighboring sheets separate. Electrochemical tests show that the two composites have different capacitive behavior. Fluorescence quenching properties of the composites were also investigated.
