▎ 摘　　要

NOVELTY - A rod-shaped porous composite material comprises graphene oxide and a cerium-containing coordination polymer. USE - Rod-shaped porous composite material is used in medicine transportation and photocatalytic degradation, sensing, absorption and separation of methylene blue. ADVANTAGE - The rod-shaped porous composite material can be prepared by simple and economical process with reduced energy consumption using easily available raw materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of rod-shaped porous composite material, which involves adding natural graphite and potassium permanganate to a mixed acid of 95% concentrated sulfuric acid and 85% concentrated phosphoric acid, dispersing in water bath at 35-55 degrees C, stirring, reacting for 72 hours, naturally cooling to room temperature, diluting obtained product with deionized water, reducing using 30% hydrogen peroxide, removing residual manganese salt and acid from the resultant product using 10% dilute hydrochloric acid, centrifuging, washing with deionized water, vacuum-drying, obtaining oxidized graphite powder, ultrasonically dispersing resultant powder in deionized water, preparing an oxidized graphene dispersion, dissolving an organic carboxylic acid in an organic solvent, obtaining organic carboxylic acid solution, dissolving an organic cerium salt in deionized water, adding the organic cerium salt aqueous solution to oxidized graphene dispersion, adding the organic carboxylic acid solution, reacting, centrifuging, washing with deionized water, and drying.
