Efficient removal of low concentration methyl mercaptan by HKUST-1 membrane constructed on porous alumina granules

A HKUST-1 metal–organic framework membrane was constructed on porous Al2O3 granules for the first time for the removal of low concentration CH3SH. The granules exhibited higher sulfur capacity than the pure HKUST-1 powders owing to the excellent dispersion of the MOF membrane on the Al2O3 substrate. The granules also showed good water resistibility.
