NOVELTY - Preparing nano composite graphene material involves carrying out electrochemical deposition of graphene in a chamber three-electrode system in an aqueous solution of 0.5-0.7 mg/ml graphene oxide. The deposition voltage is minus 1.8V, The chemically reduced graphene oxide is modified on the indium tin oxide conductive glass. The electrochemical deposition is carried out using a chamber three-electrode system in acetonitrile solution containing 0.1-0.3 moll-1 tetrabutylammonium tetrafluoroborate. USE - Method for preparing nano composite graphene material (claimed). DETAILED DESCRIPTION - Preparing nano composite graphene material involves carrying out electrochemical deposition of graphene in a chamber three-electrode system in an aqueous solution of 0.5-0.7 mg/ml graphene oxide. The deposition voltage is minus 1.8V, The chemically reduced graphene oxide is modified on the indium tin oxide conductive glass. The electrochemical deposition is carried out using a chamber three-electrode system in acetonitrile solution containing 0.1-0.3 moll-1 tetrabutylammonium tetrafluoroborate. The modified indium tin oxide conductive glass is electrochemically polymerized at a voltage of 1.35 V from 0.02 to 0.04 moll-1 5-aldehyde indole.
