The present work reports on the development of new catalysts for the production of hydrogen via the water-gas shift (WGS) reaction. In particular, the effect of Ce/La atom ratio on the catalytic performance of 0.5 wt% Pt supported on () mixed metal oxides for the WGS reaction was investigated. It was found that the addition of 20 at.% La3+ in CeO2 lattice increased significantly the catalytic activity and stability of 0.5 wt% solid. More precisely, a lower amount of “carbon” was accumulated on the catalyst surface, whereas surface acidity and basicity studies showed that had the highest concentration of labile oxygen and acid sites, and the lowest concentration of basic sites compared to the other mixed metal oxide supports ().
