Large-scale synthesis of ceria-based nano-oxides with high CO oxidation activity

We report large-scale synthesis of high surface area nano-oxides of Ce0.8M0.2O2/Al2O3 (M = Tb and Hf) possessing cuboctahedral shape of 3-5 nm size, which exhibit excellent oxygen storage capacity (OSC) and superior CO oxidation activity in comparison to the most advanced ceria-zirconia/alumina catalyst supports employed in the existing three-way-catalytic converters (TWCs).
