▎ 摘　　要

NOVELTY - Preparation of graphene-porphyrin-based organic nanomaterial comprises preparing aqueous graphene oxide dispersion, adding porphyrin and alkali, adjusting pH to 9.5-11, and heating mixture. USE - Method for preparing graphene-porphyrin-based organic nanomaterial (claimed). ADVANTAGE - The method does not use surfactants, stabilizers and reducing agent which lessens toxic to environment and reduces possibility of introducing other impurities. The nanomaterial has good electrochemical performance.
