摘要：

A simple route for decorating the external surfaces of zeolites with maghemite. nanoparticles is described. The synthesis comprises feeding of a zeolite support with different amounts of iron(III) by employing melt exchange reactions, exposure of the iron-containing solids to vapors of formic acid and finally calcination of the resulting derivatives in air to afford maghemite nanoparticles embedded in the zeolite host. The as-prepared magnetically modified solids, characterized by XRD, Mossbauer and magnetic measurements and SEM and TEM techniques, were found to retain the cation exchange capacity of the parent zeolite as well as its structural integrity.
