For the first time Fe ions were incorporated within as-synthesized surfactant-containing mesoporous host by a simultaneous detemplation and Fe-incorporation process at low temperature. The resulting materials were characterized by X-ray diffraction (XRD), thermogravimetric differential thermal analysis, N<sub>2</sub> sorption, DRIFTS, transmission electron microscopy (TEM), UV−vis diffuse reflectance spectroscopy, UV Raman, X-ray photoelectron spectroscopy, and Friedel−Crafts alkylation catalysis. The ordered mesostructure of the SBA-15 host is retained as indicated by XRD and HRTEM, and the surface areas of the Fe-SBA-15 materials are in the range of 640−853 m<sup>2</sup> g<sup>−1</sup> comparable to 784 m<sup>2</sup> g<sup>−1</sup> for the calcined host. The characterization results also indicate the presence of iron species inside the silica pores, as well as a good dispersion of the iron oxide nanoclusters within the pores of the host material. Controlled iron loading was possible to a maximum of 9 wt %. The catalyst shows significantly enhanced performance on benzylation of benzene using benzyl chloride as the alkylating agent compared to conventionally prepared Fe/SBA-15. 2008-10-23 00:00:00 mesoporou characterization results HRTEM time Fe ions surface areas iron precursor N 2 sorption alkylating agent Fe species Facile Synthesis XRD Fenton TEM benzyl chloride iron species UV Raman transmission electron microscopy reflectance spectroscopy DRIFTS SBA host material calcined host iron oxide nanoclusters silica pores Controlled iron loading
