▎ 摘　　要

NOVELTY - Preparing membrane catalytic material, comprises (1) reacting, after mixing graphene oxide dispersion liquid, organic amine and activator, carrying out dialysis treatment and ultrasonic treatment subsequently, obtaining aminated graphene oxide dispersion liquid, and (2) performing vacuum filtration of the aminated graphene oxide dispersion liquid to form a membrane, drying and performing heat treatment on the obtained membrane to obtain the membrane catalytic material. USE - The method is useful for preparing membrane catalytic material, which is useful in Knoevenagel condensation reaction (claimed). ADVANTAGE - The method: is fast and efficient; can adjust the interlayer spacing of the membrane catalytic material by adjusting the organic amine molecules modified on the surface of graphene oxide and the temperature of the heat treatment; and is suitable for Knoevenagel condensation reactions of different reaction activities and different sizes of reaction molecules; and is realized at room temperature, and the conversion rate of the reactants can reach 100% without separation and purification. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a membrane catalytic material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of the catalytic process of the membrane catalytic material according to a preferred solution (Drawing includes non-English language text).
