▎ 摘 要
NOVELTY - A catalyst preparation method involves adding 10 mg graphene and 8-50 mg phthalocyanine tetrasulfonate iron based complex to container containing triple distilled water, ultrasonically dispersing at room temperature for 6 hours, centrifuging obtained product, vacuum drying to obtain functionalized phthalocyanine tetrasulfonate iron based complex-graphene composite, placing obtained composite (20 mg) in quartz tube furnace, heat treating at 300-1000 degrees C for 3 hours in presence of argon to obtain iron-sulfur-nitrogen co-doped graphene composite material, adding obtained composite material (10 mg) and 19.3 mM chloroplatinic acid to 20 ml ethylene glycol, ultrasonically processing for 2 hours, reacting at 80-180 degrees C for 24 hours, centrifuging, washing and vacuum drying. USE - Method for preparing catalyst that is utilized in direct methanol fuel cell (claimed). ADVANTAGE - The method enables preparing catalyst with improved electrocatalytic activity for methanol oxidation and oxygen reduction reaction, excellent electrochemical stability and ability to resist carbon monoxide poisoning in a simple manner under mild and controlled conditions by enhancing synergistic coupling effect between catalytic nanoparticles and iron-sulfur-nitrogen co-doped graphene carrier. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a catalyst prepared by the method.
