摘要：

An efficient hybrid method combining chemical reduction and microwave irradiation is used to reduce graphite oxide. The hybrid reduction method achieved a carbon/oxygen ratio of 10.33 which is 2.7 times and 1.4 times higher than those obtained with chemical solution and solid-phase microwave irradiation only methods, respectively. The reduced graphene oxide obtained by the hybrid method had a conductance (1.19 x 10(4) S/m) 84.2 times higher than that by chemical solution and 15.6 times higher than that by solid-phase microwave irradiation. In addition, we reveal that microwave irradiation removes C=O bonds more efficiently than C-O bonds. (C) 2014 Elsevier B.V. All rights reserved.
