▎ 摘　　要

NOVELTY - Dihydro-pyridine-porphyrin-oxidized grapheme composite preparation involves preparing graphene oxide having a thickness of 1-2 nm. The oxidized graphite alkene and 1,4-dihydro-pyridine-porphyrin are ground to form graphene oxide with porphyrin-1,4-dihydro-pyridine mixture. The obtain mixture is dissolved in N,N-dimethylformamide and distilled water under ultrasonic treatment for 150-180 minutes to make uniform dispersion. The obtained uniform dispersion is kept to obtain 1,4-dihydro-pyridine-oxidized grapheme composite. USE - Method for preparing 1,4-dihydro-pyridine-porphyrin-oxidized grapheme composite (claimed). ADVANTAGE - The method prepares 1,4-dihydro-pyridine-porphyrin-oxidized grapheme composite with improved water solubility and stability in a simple and cost-effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic atomic force microscopic image of graphene oxide.
