Abstract
Cerium oxide nanostructures have attracted much attention due to their excellent catalytic activities. Their catalytic activity is strongly depended on their reversible Ce3+/Ce4+redox cycle and their surface defects. Among them, porous nanorods of ceria (PN-CeO2), a previously unknown nanostructured form, exhibit a very high concentration of surface defects and extremely large oxygen storage capacity of 900 μmol-O2/g. Their catalytic activity as the active components or as the supports for the highly dispersed sub-nanometric metal clusters (Pt, Pd, Au, Ru, Ir,et.al) is explored for various catalytic reactions including low temperature CO oxidation, photocatalysis, heterogeneous hydrogenation reactions and biomimetic catalysis.
