Preparation of novel 3D graphene networks for supercapacitor applications

Chemical vapor deposition is used to prepare novel 3D graphene networks, with ethanol as the carbon source. These networks are used as templates for the construction of graphene/metal oxide composite-based supercapacitor electrodes. As a proof of concept, NiO is deposited on 3D graphene networks. Th...

Description
Summary:Chemical vapor deposition is used to prepare novel 3D graphene networks, with ethanol as the carbon source. These networks are used as templates for the construction of graphene/metal oxide composite-based supercapacitor electrodes. As a proof of concept, NiO is deposited on 3D graphene networks. The product exhibits a high specific capacitance of about 816 F g−1 at a scan rate of 5 mV s−1 and good cycling performance.
