NOVELTY - The preparation of graphene oxide loaded nano molecular sieve coupling material involves mixing silicon source of nano molecular sieve and aluminum source solution at low temperature, aging above mixed solution, washing, and drying to obtain molecular sieve amorphous precursor, washing molecular sieve amorphous precursor until pH value is 8, ultrasonically mixing amorphous precursor of above molecular sieve and graphene oxide, stirring, aging, adding above aged solution with basic substance in which cation is used as nano molecular sieve pore proppant and basic group is used as pH adjuster, crystallizing the reaction solution, washing the obtained product and drying. The mass fraction of mixed graphene oxide is 1-60%. USE - Preparation of graphene oxide loaded nano molecular sieve coupling material. ADVANTAGE - The method enables preparation of graphene oxide loaded nano molecular sieve coupling material with large effective specific surface area, small accumulation structure, short gas diffusion path, high micropores utilization efficiency and high composite performance by economical and environmentally-friendly process.
