Abstract
Graphene aerogels with high conductivity and surface areas including a method for making a graphene aerogel, including the following steps: (1) preparing a reaction mixture comprising a graphene oxide suspension and at least one catalyst; (2) curing the reaction mixture to produce a wet gel; (3) drying the wet gel to produce a dry gel; and (4) pyrolyzing the dry gel to produce a graphene aerogel. Applications include electrical energy storage including batteries and supercapacitors.

A method comprising:
- preparing a reaction mixture comprising a graphene oxide (GO) suspension and at least one catalyst;
- curing the reaction mixture to produce a wet gel;
- drying the wet gel to produce a dry gel;
- and pyrolyzing the dry gel to produce a graphene aerogel.
A method comprising the step of providing a reaction mixture comprising at least one graphene precursor, converting the graphene precursor to a graphene aerogel in a sol gel process.
