▎ 摘　　要

NOVELTY - Preparing sulfonated graphene oxide/polymer porous catalytic membrane involves adding dry sulfonated graphene oxide and a pore-forming additive to a solvent to ultrasonically disperse to obtain a sulfonated graphene oxide solution, adding the polymer to the sulfonated graphene oxide solution, and fully stirring. The sulfonated graphene oxide/polymer solution is obtained by standing defoaming, and sulfonated graphene oxide/polymer solution is used as the casting solution, where sulfonated graphene oxide/polymer porous catalysis is prepared by the immersion precipitation phase transformation process. USE - Method for preparing sulfonated graphene oxide/polymer porous catalytic membrane for catalytically degrading cellulose (claimed). ADVANTAGE - The method enables to prepare sulfonated graphene oxide/polymer porous catalytic membrane which is excellent catalytic performance, easy to operate, and provides an effective method of using mass of cellulose. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for catalytically degrading cellulose, which involves using sulfonated graphene oxide/polymer porous catalytic membrane as a catalyst, and performing dynamic cyclic catalytic reaction of cellulose, and dissolving in the ionic liquid at 50-170 degrees C.
