As claimed by the invention, the process consists in ultrasonically treating a mixture of resorcinol dissolved in deionized water with graphene oxide, for 15...20 min, after which formaldehyde is added under magnetic stirring, followed by the stages of gelling, ageing, drying and carbonizing at a temperature of 700...800°C for 8...10 h, to result in a composite carbonic xerogel with graphene oxide.
