NOVELTY - The method involves taking a molybdate aqueous solution as an electrolyte, and taking two pieces of graphite paper as an anode and a cathode respectively to form an electrolytic system, electrifying, and carrying out electrochemical anode stripping to obtain an electrolytic solution containing a graphene precursor. The electrolytic solution containing the graphene precursor is purified to obtain the graphene dispersion liquid. The molybdate is several of sodium molybdate and ammonium molybdate. The concentration of molybdate in the aqueous molybdate solution is between 0.015 and 1.0M. The graphite paper is cleaned with absolute alcohol before being used as the anode and cathode, respectively. The anode and the cathode are placed in parallel in the electrolyte and connected to both poles of a dc power source to form an electrolytic system. The voltage of the direct current power supply ranges from +9V to + 10V. USE - Method for preparing graphene by electrochemical anode stripping suitable for industrial production widely used in fields of transistors, batteries and supercapacitors, biomedicine, biosensors, electrothermal films and catalysis. ADVANTAGE - The method has good water solubility and stability, is simple to operate, environmentally-friendly, pollution-free, safe, non-toxic, low in cost and energy consumption, and ensures that no toxic gas is generated in the electrolysis process, and only a simple water electrolysis reaction is performed to generate hydrogen and oxygen, so that the method is green and pollution-free. The graphite paper electrode is low in price and convenient and easy to obtain. The innovativeness is high, and molybdate remained on the graphene precursor is easy to remove. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic photo of the graphene dispersion dispersed in deionized water, where the left and right sides are compared before and after being placed for two months.
