▎ 摘　　要

NOVELTY - An aerogel based on graphene doped with nitrogen and boron. USE - As an aerogel, which is used as electrode, preferably as oxygen consumption electrode, in batteries, in supercapacitors, preferably in all solid state supercapacitors, or as catalysts, preferably as electrocatalysts for oxygen reduction reactions (claimed). ADVANTAGE - The aerogel shows a threedimensional (3D) open macroporosity with interconnected network structure, high specific surface area, excellent electrical conductivity, mechanically flexibility and light weight. These features render the fully interfacial wettability of electrolyte for rapid ion diffusion in the bulk electrode and fast electron transport in the 3D graphene network. The solid state supercapacitors (ASSSs) based on aerogels show high specific capacitance, good rate capability, enhanced energy density or power density in comparison with undoped graphene aerogels (GAs), only N- or B- doped GAs, and layer-structured graphene paper (GP). The aerogel can be produced in an easy way, e.g. by a hydrothermal assembly of an aqueous solution of graphene oxide containing flake sizes ranging between hundreds of nanometers and several micrometers followed by freeze-drying. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) producing an aerogel involving treating graphene oxide with at least one component (A1) containing nitrogen and at least one component (B1) containing boron and/or with at least component (C1) containing both nitrogen and boron in order to obtain graphene doped with nitrogen and boron; (2) an electrode made from the aerogel; (3) all solid state supercapacitor (ASSS) containing the aerogel or the electrode; (4) a catalyst containing the aerogel; and (5) Graphene doped with nitrogen and boron.
