▎ 摘  要

NOVELTY - Production of hydrogen involves mixing phosphoric acid and sulfuric acid, placing resultant in water bath, stirring, heat-preserving, adding potassium permanganate, heating, cooling, adding deionized water and hydrogen peroxide, dripping graphite solution, separating supernatant, adding hydrochloric acid, centrifuging, dialyzing, adding graphene oxide, titanium dioxide particles and sodium hydroxide, reacting, washing, calcining, and assembling dual-chambered microbial fuel cell using resultant product as cathode, proton exchange membrane and tin foil. USE - Production of hydrogen (claimed). ADVANTAGE - The method enables simple simultaneous catalytic production of hydrogen and generation of electricity. DETAILED DESCRIPTION - Production of hydrogen involves mixing 4 g graphite powder and 40 g sodium chloride in a mortar, grinding for 3 hours, adding resultant material to 1 L beaker, adding 900 ml deionized water, stirring for 30 minutes, filtering, adding 900 ml deionized water, filtering, mixing filtrate with silver nitrate solution, adding 55 ml phosphoric acid and 480 ml sulfuric acid, placing resultant in water bath, stirring for 30 minutes, heat-preserving at room temperature for 8 hours, adding 25 g potassium permanganate, stirring for 30 minutes, heating to 50 degrees C, cooling to room temperature, adding 700 ml deionized water and 6 ml hydrogen peroxide, dripping graphite solution, separating supernatant, adding 10 %mass hydrochloric acid to resultant residue, centrifuging, dialyzing, adding 0.4 g graphene oxide, 0.1 g titanium dioxide particles and 4 g sodium hydroxide solid, ultrasonically processing, stirring for 12 hours, reacting at 120 degrees C for 24 hours, washing using deionized water, vacuum-drying at 40 degrees C for 10 hours, calcining at 400 degrees C for 2 hours, ultrasonically processing for 30 minutes, and assembling dual-chambered microbial fuel cell using resultant product as cathode, proton exchange membrane, tin foil and cathode seal.
