▎ 摘　　要

NOVELTY - A supramolecular hybrid hydrogel comprises ferrocene-amino acid gel factor and graphene oxide co-assembled by non-covalent bonds, where it has three-dimensional network-shaped structure. USE - Supramolecular hybrid hydrogel used for preparing graphene aerogel (claimed). DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of supramolecular hybrid hydrogel comprising taking graphene oxide aqueous solution, adjusting pH to neutral or alkaline by phosphate buffer solution, ultrasonically dispersing ferrocene-amino acid powder in dimethyl sulfoxide to obtain stock solution, adding graphene oxide in phosphate buffer solution to obtain mixed solution, shaking, ultrasonically processing and standing; and (2) preparation of graphene aerogel comprising taking supramolecular hybrid hydrogel as raw material, performing in-situ synthesis, hydrothermally treating and doping with nitrogen and ferrous-ferric oxide nanoparticles to obtain three-dimensional structure.
