▎ 摘　　要

NOVELTY - A 3A molecular sieve is activated. Graphene oxide is activated and ultrasonically dispersed, to obtain graphene suspension. The activated 3A molecular sieve and graphene suspension in mass ratio of 1:5-1:20 are fed to hydrothermal reactor and hydrothermally reacted at 180-220 degrees C for 8-12 hours. The reaction product is filtered, dried and evacuated in vacuum oven, to obtain graphene-molecular sieve composite gas purification material. USE - Preparation of graphene-molecular sieve composite gas purification material (claimed). ADVANTAGE - The method enables preparation of graphene-molecular sieve composite gas purification material with high specific surface area, selectivity, porosity and pore diversity.
