▎ 摘  要

NOVELTY - Production of three-dimensional graphite/porphyrin complex redox electro-catalyst comprises: (i) carrying out heat treatment of three-dimensional graphene at 300-800 degrees C for 30-90 minutes; (ii) stirring the graphene after heat treatment to mix and react with porphyrin in liquid phase, centrifuging, cleaning the product and drying under vacuum to obtain the three-dimensional graphene/porphyrin complex redox electro-catalyst. USE - The method is useful for the preparation of graphite/porphyrin complex redox electro-catalyst (claimed). ADVANTAGE - The method uses three-dimensional graphene for heat treatment, which improves the performance of the redox catalyst. The catalyst: has long term stability and anti-methanol catalytic activity; is cheap; has simple preparation; and replaces the noble metal, platinum, which is used as a redox catalyst in commercial fuel cells.
