▎ 摘　　要

ZnO/reduced graphene oxide composites were fabricated by coassembly between honeycomb-like ZnO particles and reduced graphene oxide sheets via electrostatic interaction, in which the ZnO particles acted as spacers to keep the neighboring graphene sheets separate. The composite was characterized using X-ray diffraction and scanning electron microscopy, and was used for investigation of electrochemical capacitive behaviors. The hybrid material showed enhanced capacitive performance (231.3 F/g at 0.1 A/g), and remained 86% of the initial capacity after 300 cycle, which predicted its potential application in energy storage.
