Mixed zeolite hybrids combining the MFI structure with exfoliated MWW monolayers

Zeolite monolayers in solution, reported recently for the framework MWW, enable unprecedented synthetic capabilities that include preparation of molecularly intimate mixtures different zeolite topologies. As a demonstration, MWW-MFI hybrid materials were synthesized by two methods: in-situ crystallization MFI adding template and silica to solutions MWW obtained from MCM-56, ex-situ mixing layers with crystals. Catalytic activity was similar undiluted pure despite high content siliceous MFI, which inert. This suggests do not provide optimal packing accessibility active sites can be more efficiently utilized combination other components. The mixture MCM-56 crystals 50% less active. Practical benefits may possible combining frameworks types catalysis sorption applications. characterized standard X-ray powder diffraction, TEM SEM imaging, gas adsorptions FTIR, showed properties both features acid porosity. • Exfoliated nanosheets solution used prepare mixed hybrids MFI. In-situ synthesis involved presence nanosheets. Ex-situ combined did diminish dilution phase. Physical zeolites
