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 nanorods, having 5–7 nm diameter, exhibit unprecedented low‐temperature oxygen‐storage capacity (OSC) performance.
