Ultrafine cerium oxide nanorods are produced from rapidly liquid quenched Ce-Al alloy precursors by a corrosion method through the selective leaching of Al and the oxidation of Ce in an alkaline medium under mild conditions. The obtained nano rods, having 5-7 nm diameter, exhibit unprecedented low-temperature oxygen-storage capacity (OSC) performance.
