Abstract
A relatively new class of three-dimensional ordered mesoporous silicates, KIT-6,
incorporated with Earth-abundant metals such as Zr, Nb, and W (termed as M-KIT-6),
show remarkable tunability of acidity and metal dispersion depending on the metal content, type,
and synthetic method. The metal-incorporation is carried out using one-pot synthesis procedures
that are amenable to easy scale-up. By such tuning, M-KIT-6 catalysts are shown to provide
remarkable activity and selectivity in industrially-significant reactions, such as alcohol dehydration,
ethylene epoxidation, and metathesis of 2-butene and ethylene.We review how the catalytic properties
of M-KIT-6 materials may be tailored depending on the application to optimize performance.
