✦ Synopsis

Encapsulation of Fe(phen) 3 in zeolite Y via directly complexing hydrothermally synthesized FeY with phenanthroline (abbreviated as phen) was first tried. The as-prepared materials have been characterized with XRD, FTIR, diffuse reflectance UV-vis spectroscopy (DRS), TG/DTA and ICP techniques. Further, their catalytic performance was also explored with cyclohexane oxidation and styrene oxidation as model reactions. It has been shown that Fe(phen) 3 is stably immobilized on zeolite Y, as proved by its basically unchanged catalytic property within three reaction recycles for the oxidation of cyclohexane. The as-prepared Fe(phen) 3 /Y exhibits much stronger oxidation ability than FeY and Fe(phen) 3 /Y prepared by the conventional flexible ligand method where Fe ions were introduced into the host by ion-exchanging Na + cations.
