Fe/Al synergy in FeOnanoparticles supported on porous aluminosilicate materials: excelling activities in oxidation reactions

A synergetic Fe-Al effect in Fe 2 O 3 nanoparticles supported on mesoporous aluminosilicates compared to pure siliceous silicates has been demonstrated, for the first time, by a remarkably superior catalytic activity of the former in the microwave-assisted selective oxidation of benzyl alcohol to benzaldehyde. This significant finding, that also deeply influences the acidity of the materials (increasing total and particularly Lewis acidity), can have important consequences in the improved efficiency of these systems in related oxidations as well as in acid catalysed processes. A remarkable Fe/Al interaction in iron oxide supported nanoparticles on aluminosilicates significantly improved the activities of such materials in oxidation reactions.
