摘要

A facile method to prepare reduced graphene oxide (M-rGO) nanosheets with enhanced electrochemical performance has been established by using Mg powder as the reductant. The structural, morphological and electrochemical properties of the M-rGO have been characterized. The prepared M-rGO possesses well-developed nano-porous structure and superior surface characteristics. Electrochemical analyses show that the M-rGO has a maximum specific capacitance of 577.4 F g(-1) at the scan rate of 1 mV s(-1), and an excellent rate performance of 324.9 F g(-1) at 1 V s(-1). The CV curves of M-rGO can keep rectangular in shape even at a scan rate of 500 mV s(-1) without obvious distortion. Such outstanding electrochemical performances of M-rGO can be attributed to both the presence of nano-pores in M-rGO and the pseudocapacitance arising from residual oxygen-containing functional groups.
