▎ 摘  要

NOVELTY - The method involves initiating (102) scan by potentials applied on graphite electrode at preset scan rate and at preset negative maximum and positive maximum potential interval. The potential scan is terminated (107) at initial maximum negative potential value. The graphene based electrode is generated (101) without removing graphite electrode from solution by submersion of graphite working electrode in electrochemical system into solution having electrolyte-including mono-protic and poly-protic acids, bases, salts of predetermined concentrations and mixtures at different rates. USE - Alternate voltammetry method. ADVANTAGE - The graphene based electrode is generated in a single step, in order to be used in energy and material sectors. The electrical conductivity and mechanical strength of the graphene based electrodes can be improved. The significant application fields such as the material industry as energy storage systems can be ensured. The graphene electrode synthesis can be realized synchronously without requirements of automation system during generation. The ease and cheapness of the process can be allowed. DETAILED DESCRIPTION - The potential scan is initiated (103) from the negative maximum potential area including from the cathodic area, and the rise of oxidation in positive area including anodic area is determined, while progressing to positive area from negative area. The graphite electrode is transformed (104) to graphene oxide by the oxidation arising in the anodic area. The oxidation arising in the anodic area is followed, and the continuation of scan at negative potential area as returning from the positive maximum potential value is determined (105). The graphene oxide is transformed (106) to graphene by the reduction of types oxidized in the negative area through the potential scan in negative direction. The increase of graphene layer through the application between the cycles is achieved. The layer structure and number of the graphene are completely controlled. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the alternate voltammetry process.
