Abstract: Mesoporous ferrisilicates MFS-n (n = Si /Fe) with different Si/Fe molar ratio (Si/Fe = 20, 135) were synthesised by the assembly of Fe MFI nanoclusters with triblock copolymers in strongly acidic media. Au/MFS-n catalysts were prepared by deposition-precipitation with urea (DPU) with a loading of gold of 1 wt%. They were characterised by various techniques including XRD, BET, FT-IR spectroscopy; diffuse reflectance UV-vis (DRUV-vis), TPR. Total oxidation of toluene was investigated on MFS-n and Au/MFS-n. The catalytic activity of MFS-n materials for total toluene oxidation is considerably enhanced as the iron content increases. The presence of gold improves the catalytic activity of MFS-n towards the combustion of toluene, the extent of this effect depending on the Si/Fe molar ratio. The catalysts are totally selective for CO2 and H2O.
