▎ 摘　　要

In this work, one-dimensional CoMoO4 center dot 0.9H(2)O nanorods grown on reduced graphene oxide hybrid composites (CoMoO4 center dot 0.9H(2)O-rGO) with good electrochemical properties have been synthesized by a simple and environmentally friendly hydrothermal synthesis procedure. The conductive graphene not only improves the electron conductivity of the overall electrode but also provides strong synergistic effects with Faradaic pseudo-capacitance (CoMoO4 center dot 0.9H(2)O). Meanwhile, rGO can act as a buffer for the volume change, which can provide an assurance for better cycling performance of the CoMoO4 center dot 0.9H(2)O-rGO hybrid composites. An exceptionally high specific capacitance of 802.2 F g(-1) at a current density of 1 A g(-1) and good cycle stability with capacitance retention of similar to 86.3% after 5000 cycles is obtained for the CoMoO4 center dot 0.9H(2)O-rGO composites. The remarkable electrochemical performance can make the CoMoO4 center dot 0.9H(2)O-rGO composites one of the most competitive electrode materials for electrochemical energy storage.
