▎ 摘　　要

NOVELTY - Electrosynthesizing graphene composite electrode comprises (1) placing graphene oxide with an interface zeta potential of 20 to -35 mv in container, adding pyrrole, adding an organic sulfonate hole-expanding dopant, adjusting the pH to 2.5-4.5 with benzenesulfonic acid, remainder being water, ultrasound or stirring to obtain black nanosol, storing under nitrogen, where the final concentration of graphene oxide is 0.3-0.8 g/l, final concentration of pyrrole is 0.1-0.5 mol/l and final concentration of the agent is 0-40 g/l and (2) using a three-dimensional mesh-shaped conductive support frame as the working electrode, immersing in a black nanosol through nitrogen at a current density of 2-5 mA/cm2 and an electric quantity of 0.5-20 C/cm2, 20-40 degrees C, depositing black nanosol and polymerizing on the three-dimensional network conductive support framework, rinsing with distilled water to removing impurities and drying to make graphene composite electrode. USE - The method is useful for electrosynthesizing graphene composite electrode. ADVANTAGE - The electrode: has even distribution of components and easy storage; and is suitable for electroabsorption and desalination operations compared with conventional porous carbon electrode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene composite electrode.
