NOVELTY - Preparing graphene-doped ruthenium(IV) oxide-based porous electrode comprises e.g. blasting titanium plate or foam nickel matrix, degreasing, etching, rinsing with deionized water, then adding into the ethanol solution, adding acidified graphene into a ruthenium trichloride solution, and continuing ultrasonic oscillation, and mixing graphene-added ruthenium trichloride solution and non-precious metal oxide precursor ultrasonically, drying under infrared lamp, placing at 300 degrees C in a muffle furnace for pre-oxidization for 10 minutes, and air cooling to obtain final product. USE - The method is useful for preparing graphene-doped ruthenium(IV) oxide-based porous electrode (claimed). DETAILED DESCRIPTION - Preparing graphene-doped ruthenium(IV) oxide-based porous electrode comprises (i) blasting TA2 titanium plate or foam nickel matrix, degreasing, etching, rinsing with deionized water, then adding into the ethanol solution, (ii) dissolving 0.2-0.6 mg/cm2 ruthenium loaded ruthenium trichloride in anhydrous ethanol completely by ultrasonic vibration, (iii) taking 0.2-0.6 g/cm2 graphene and acidifying with graphene by adding 0.5 ml/cm2 concentrated hydrochloric acid, and mixing the acidified graphene into a ruthenium trichloride solution, and continuing ultrasonic oscillation, (iv) dissolving precursor of the non-precious metal oxide in a molar ratio of precious metal ions to non-precious metal ions of 1:4-4:1 in anhydrous ethanol or n-butanol alcohol solution, (v) mixing the graphene-added ruthenium trichloride solution and non-precious metal oxide precursor ultrasonically with shaking until completely dissolved into a coating solution having a metal ion concentration of 30 wt.%, and (vi) coating the coating liquid on the titanium plate or the foam nickel, drying under infrared lamp, placing at 300 degrees C in a muffle furnace for pre-oxidization for 10 minutes, and air cooling until all the liquid is exhausted, and reacting at 300-380 degrees C for 1-6 hours to obtain final product.
