Several metals (e.g. Ni, Rh, Pt) have been supported on La2O3 and used in the CO22O3 and used in the CO2 + CH4 reaction. Very few kinetic and mechanistic studies have been published. The work of Verykios and co-workers  for Ni/La2O3 and our own on Rh/La2O3  coincide in the role of the lanthanum oxycarbonates during this reaction. In the latter case, the Rh dispersion is very low, a difficulty that was overcome when La2O3.SiO2 was the support. In this work through the comparison of the characterization and kinetic data obtained with both systems, we hope to improve the understanding of lanthanum-based dry reforming catalysts. the comparison of the characterization and kinetic data obtained with both systems, we hope to improve the understanding of lanthanum-based dry reforming catalysts. the lanthanum oxycarbonates during this reaction.
