Rhodium catalysts were active for the dry reforming of methane reaction in membrane reactors [1]. Furthermore, when the La2O3-SiO2 support was used the Rh and Ru formulations were catalytically stable and did not produce carbonaceous residues. In this work, we report the results obtained with novel catalysts, Rh/CaO-SiO2. The fresh catalysts were characterized by XRD, TPR, FTIR and CO and hydrogen chemisorption. FTIR spectroscopy with CO as a probe molecule was used to study the promoter oxide role
