Copper-based nanomaterials and applications

By FTIR, XPS and TDMS experiments, CO2 dissociation at room temperature has been stated on Ln2O3-promoted Rh/Al2O3 catalysts (Ln = La, Lu). Both the rare earth cation and the rhodium metal are involved in the intermediate steps of the process. In the cooperative model proposed, the surface hydroxylation plays the key role on the generation of strong Lewis acid centres at the surface which are essential for the carbon dioxide dissociation.
