▎ 摘　　要

NOVELTY - Preparing graphene-iron doped porous carbon composite catalyst involves mixing 2-fluoroaniline, ferric oxide and graphene with deionized water and then stirring the mixed material. The stirred material is dispersed ultrasonically to obtain dispersion liquid and then the dispersion liquid is subjected to perform hydrothermal reaction. The reacted material is cooled, filtered, cleaned and dried to obtain poly-2-fluoroaniline-graphene sheet. The obtained sheet is kept in quartz tube furnace under nitrogen gas atmosphere at 700-900 degrees C and then cooled to obtain the desired product. USE - Method for preparing graphene-iron doped porous carbon composite catalyst used in fuel battery (claimed). ADVANTAGE - The method enables to prepare graphene-iron doped porous carbon composite catalyst with large specific surface area, good catalytic performance, resistance to methanol poisoning ability, good durability and high stability.
