MCM-22 Zeolite
MCM-22 Zeolite
Mesoporous Molecular sieve MCM-22 zeolite is a novel microporous molecular sieve with MWW structure. In the molecular sieve layered structure of the upper and lower surfaces are covered with a high density of the hole structure, the whole structure for the twelve yuan ring opening, the depth of about 0.7 nm.
