▎ 摘  要

NOVELTY - Y molecular sieve/graphene composite material comprises Y-type molecular sieve, where the mass content of the graphene is 1-40%, preferably 5-25%. USE - Y molecular sieve/graphene composite material for carbon monoxide adsorption separation process. ADVANTAGE - The Y molecular sieve/graphene composite material is eco-friendly and has high efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing Y molecular sieve/graphene composite material, which involves mixing the silicon source, aluminium source, alkali source and water to prepare precursor gel, where silicon source is counted by silicon dioxide, adding graphene into the precursor gel obtained to mix, and then crystallizing to obtain the Y molecular sieve/graphene composite material. DESCRIPTION OF DRAWING(S) - The drawing shows a SEM (scanning electron microscope) graph of Y molecular sieve/graphene composite material prepared in Example 1.
