ZrO2–PMA materials are active in the oxidation reaction of
various industrially important alkenes using hydrogen peroxide
as oxygen donor. The ZrO2 loaded with ꢂ37 wt% of PMA
demonstrates remarkable catalytic activities which are compa-
rable to those of free PMA clusters, while exhibiting exceptional
durability and reusability in oxidation reactions, more than
analogously impregnated catalysts. These results indicate that
such materials should have great application potential in
oxidation catalysis. Because of the well-ordered pore structure,
size- and shape-selective catalysis may also be envisioned.
