Hydrothermal synthesis of boron-free Zr-MWW and Sn-MWW zeolites as robust Lewis acid catalysts

Boron-free Zr-MWW and Sn-MWW metallosilicates were synthesized via dual structure-directing agent-facilitated crystallization, which demonstrated unique catalytic behavior in Meerwein–Pondorf–Verley and Baeyer–Villiger oxidation reactions.
