▎ 摘　　要

NOVELTY - Preparing graphene/single-walled carbon nanotube composite flexible electrode of supported catalyst comprises (i) preparing high-purity single-walled carbon nanotubes by DC arc discharge method, pumping air pressure in arc reaction chamber to a vacuum state, discharging between anode carbon electrode rod doped with iron catalyst and cathode pure carbon electrode rod, pumping air pressure in tube furnace to a vacuum state, passing dry air into tube furnace to standard atmospheric pressure, use heating equipment to heat temperature in the tube furnace to 300-420°C, heat preserving for 30-60 minutes and closing heating equipment; and (ii) preparing catalyst-loaded graphene, dissolving quantitative catalyst precursor and graphene oxide powder in deionized water, heating solution system to 100°C in a water bath, adding excess reducing agent into solution system, and reacting; and (iii) preparing catalyst-supported graphene/single-walled carbon nanotube composite flexible electrodes. USE - The electrode is useful for catalytic oxidation reaction of glucose by graphene flexible electrode of the loaded catalyst/single-wall carbon nano-tube (claimed). ADVANTAGE - The electrode overcomes the problem that highly crystalline single-walled carbon nanotubes are difficult to modify and the conductivity of graphene prepared by redox method, problem of poor flexibility, or applied to glucose fuel cells to convert the chemical energy in glucose into electrical energy. The method is economical, environmentally friendly and has simple device, and does not need to use highly toxic or strong oxidizing chemicals. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for catalyst-supported graphene/single-walled carbon nanotube composite flexible electrode.
