Graphene oxide derived carbons (GODCs): synthesis and gas adsorption properties

Abstract

We report the synthesis of a range of high surface area graphene oxide derived carbons (GODCs) and their applications toward carbon capture and methane storage. We obtain largely increased surface areas up to nearly 1900 m² g⁻¹ for GODC samples from 10 m² g⁻¹ of precursor graphene oxide (GO). Our GODCs reveal favourable gas adsorption capacities compared to other high surface area carbons. We show that producing high surface area carbons from GO precursor is a viable method, and the porosity parameters are easily tuneable for their potential gas adsorption applications.
