Supercapacitor Electrodes Made of Exhausted Activated Carbon-Derived SiC Nanoparticles Coated by Graphene
Graphene
has been obtained at atmospheric pressure and low temperature
on exhausted activated carbon-derived SiC nanoparticles. The graphene’s
growth, traced by online analyzers, has been obtained from an external
source of carbon, in particular by methane/hydrogen chemical vapor
deposition (CVD). Recycled SiC has been chosen as growth substrate
to carry out a convenient process and to increase the added value
of the recycled, combining the favorable properties of different substances.
Therefore, the SiC powder and the composite material obtained have
been carefully characterized by the combined use of different techniques
and tested as supercapacitor electrodes. The results show a very high
capacitances up to 114.7 F/g for SiC alone and three times higher
in the presence of graphene with an excellent cycle stability
