Methylcellulose-assisted synthesis of a compact and thin NaA zeolite membrane

摘要

A compact and thin NaA zeolite membrane was prepared by utilizing methylcellulose (MC) as space confinement additive under microwave heating. MC played the roles of patching the defects and reducing the thickness of membrane, which improved obviously the permselectivity and, particularly, ensured an above 10 ~(?6) mol m ~(?2) × s ~(?1) × Pa ~(?1) of H _(2) permeance.
