dc.description.abstractFe/SiO 2 and Rh-Fe/SiO 2 catalysts with increasing Fe/Rh ratio have been prepared and characterized by TEM, XRD, oxygen adsorption and Mössbauer spectroscopy. It was confirmed that Fe/SiO 2 catalysts cannot be reduced under hydrogen flow, to more than 50 % whatever the temperature in the 200-500 °C range and shown that the presence of even a small amount of Rh (Fe/Rh ≤2,000) promoted the reduction of iron up to 85-95 %. This promoting effect also took place with a Fe/SiO 2 + Rh/SiO 2 physical mixture (Fe/Rh B2,000). Therefore, the occurrence of a hydrogen spillover effect may be involved in the observed process. © 2012 Springer Science+Business Media, LLC.
