▎ 摘　　要

NOVELTY - Preparing heteropoly acid catalyzed graphene aerogel comprises (i) dissolving phosphomolybdic acid in water to obtain phosphomolybdic acid solution of 0.01-0.05 mmol/ml, dissolving the aromatic amine in water to obtain aromatic amine solution of 0.1-0.5 mmol/ml, mixing the phosphomolybdic acid solution and the aromatic amine solution, obtaining mixed solution, adding 1-6 mg/ml graphene oxide dispersion into the mixed solution, and allowing to stand to obtain graphene hydrogel, where the volume ratio of the phosphomolybdic acid solution, the aromatic amine solution, and the graphene oxide dispersion is 1:1-6:1-6, the aromatic amine includes p-phenylene diamine, 2,6-diaminopyridine, melamine and/or 2,6-diaminopurine; and (ii) washing the graphene hydrogel with water, pre-freezing, and freeze-drying to obtain graphene gas gel. USE - The graphene aerogel is useful for supercapacitor as electrode material (claimed). ADVANTAGE - The method is simple and easy, and consumes short time and low energy, and ensures wide raw material source and low price, and excellent performance aerogel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for heteropoly acid catalyzed graphene aerogel is prepared by above mentioned method.
