▎ 摘　　要

NOVELTY - Manufacture of graphene oxide/graphene aerogel involves preparing an oxidized graphite precursor, controlling graphite-oxide nature such as number of functional groups, dispersion stability, concentration and size, subjecting the oxidized graphite precursor to hydrothermal/solvothermal process, drying and optionally reducing. The graphene oxide/graphene aerogel has carbon-based sponge-like structure and large pores. USE - Manufacture of graphene oxide/graphene aerogel used for adsorption and removal of hydrophobic contaminants e.g. rhodamine (all claimed) in wastewater and waste oil. ADVANTAGE - The method enables efficient manufacture of graphene oxide/graphene aerogel having excellent workability, elasticity and flame retardance.
