USE - The method is useful for producing titanium-graphene electrode utilizing graphene oxide (claimed). ADVANTAGE - The method does not require any auxiliary device (claimed). DETAILED DESCRIPTION - Producing titanium-graphene electrode utilizing graphene oxide comprises (i) preparing graphene oxide: taking graphite powder into a beaker, stirring in ice water bath, adding sodium nitrate into the beaker, where the mass ratio of graphite powder and sodium nitrate is 2:1, adding sulfuric acid, where the graphite powder concentration with sulfuric acid is 43.5 mg/ml, adding potassium permanganate slowly, where the mass ratio of graphite powder and potassium permanganate is 1:3, allowing to stand for 5 minutes, removing form the ice water bath, heating to 35 degrees C for 30 minutes, adding water slowly, where the graphite powder concentration with water is 21.7 mg/ml, stirring for 15 minutes, adding 3 wt.% aqueous solution of hydrogen peroxide at 60 degrees C until the bubbles disappear, centrifuging the precipitate to a pH of 3-4 and freeze drying to obtain graphene oxide powder, (ii) producing the electrode: sanding titanium plate with 100-180 sandpaper, rinsing good polished titanium plate with deionized water for 2-5 times, drying the plate, treating template with bubble membrane electrode, preferably with graphene oxide, blow drying the titanium electrode plate as template, preparing 2-20 mg/ml solution of graphene oxide, adding sodium dodecylbenzenesulfonate as surfactant, where the concentration of sodium dodecylbenzenesulfonate is 0.02 mg/ml, immersing the titanium plate vertically or horizontally in graphene oxide solution as a template, soaking for 1-30 minutes, removing gently, drying naturally to form a film of graphene oxide foam, where the principle of film forming surface is: (a) arranging the amphiphilic molecules of foam membrane orderly in a two-dimensional assembly structure, adding surfactant solution and bubbling or expanding air in the air/water interface, (b) drying the foam film of water in the gap and discharging into air, (c) evaporating solution having amphiphilic compounds forming pores to obtain dry film, and (iii) taking out the titanium film having a foam plate after completing the reaction and drying naturally to obtain product.
