Research on the Preparation of Graphene Aerogel Materials from Graphene Oxide Reduced by Vitamin C

Abstract

This study focuses on the preparation of graphene aerogels with a porous structure using graphene oxide as the precursor and vitamin C as the reducing agent. The reduction of graphene oxide is achieved by heating a solution containing vitamin C, followed by drying to obtain the graphene aerogel. The resulting material exhibits a low density and some compressive strength. Various characterization tests, including oil-water separation and combustion experiments, demonstrate the aerogel’s excellent oil absorption and combustion properties. The oil adsorption capacity of the graphene aerogel was found to average 50 mg/mg. These findings suggest that the prepared graphene aerogels possess remarkable oil absorption capabilities, efficient oil-water separation performance, and can be regenerated through combustion, highlighting their promising potential for diverse applications.
