▎ 摘　　要

A triethylene glycol (trigol) based simple approach is reported for the reduction of graphite oxide (GO). This protocol produces high quality graphene which we term as trigol reduced graphene (TRG) and its relevant properties including electrical conductivity and energy storage capacity are comparable to those of graphene obtained by the conventional hydrazine based approach. The achieved specific capacitance for TRG is 130 F g(-1) with an energy density value of 18 W h kg(-1). This work opens up a new promising synthetic route for the development of graphene and graphene based nanocomposites for various energy related applications.
