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‐te...
