Abstract

Iron oxide doped silica films and powders with highly ordered mesostructures of extraordinary temperature stability (up to 1000 °C) and iron loading of up to 6 atom% were produced by the use of novel iron alkoxide-coordinated surfactants. Wormhole-like, 2d-centered rectangular, orthorhombic and lamellar mesostructures were obtained by variation of the molar ratios of the metal–surfactant complexes. The influence of a subsequent heat treatment was studied by GI-SAXS, TEM, XRD, and nitrogen sorption techniques. The molecular composition of the films was studied by XPS and EXAFS.
