Abstract
MCM-48 mesoporous molecular sieves containing iron(III) were obtained using a direct sol-gel route followed by removal of the cetyltrimethyl ammonium hydroxide template before calcination. UV-visible, ESR, and X ANES spectroscopies show that iron mostly occupies tetrahedral sites o f the siliceous walls. The formation of oxide nanoclusters in the chan nels is favored in the presence of the organic template molecules duri ng calcination.
