Abstract

Aqueous ion-exchange and impregnation procedures were used to isolate MnS in laumontite zeolite. XRD and FTIR measurements suggest that the clusters are formed inside the zeolite channels. ED analysis and Kubelka-Munk spectra proved that the impregnation procedure favors the formation not only of MnS clusters but also the formation of metal nanoparticles. Dispersion in the dimension of MnS clusters and metal nanoparticles was evidenced..
