Abstract
In this work, graphene oxide (GO) was directly reduced by copper to reduced graphene oxide (RGO) and formed a highly uniform RGO film on copper foil or copper-modified titanium (Ti) substrate. The characterization of as-prepared RGO film by FTIR and XRD indicated that GO was partially reduced by copper while some oxygen-containing groups still remained. The conductivity of the RGO film was improved from 3.76 × 103 to 2.98 × 104 S/m after it was further electrochemically reduced due to the removal of additional oxygen groups. The graphene supercapacitor prepared with this method exhibited better performances in a neutral aqueous electrolyte compared with that reported for graphene electrodes prepared by other fabrication methods.
