Noble metals are more active than Ni for the dry reforming of methane. As a bonus, ruthenium is much cheaper than rhodium. Furthermore, when the lantana support is used the Ru formulations are catalytically stable and do not produce carbonaceous residues [1]. Lantana helps to clean the catalyst surface by reacting with the carbon formed during the reforming of methane [1,2]. In this case, the Ru dispersion is very low, a difficulty that could be overcome when La2O3-SiO2 is used as a support. The goal of this work was to study how La2O3 loading affects the metal dispersion and the catalyst activity and stability
