A facile coprecipitation and deposition precipitation method were used for synthesis of nanosized Ce0.8Tb0.2O2-delta (CT) and Ce0.8Tb0.2O2-delta/TiO2(CTT) solid solutions, respectively. The synthesized materials were characterized by various state-of-the-art techniques and evaluated for CO oxidation activity. Formation of CT solid solution was confirmed by XRD and Raman, and nanocrystalline nature by TEM. Characterization results further suggested formation of a new pyrochlore phase between TiO2 and TbO2 at 1073 K, and the presence of Ce3+ associated with lattice defects in all samples. Catalytic results showed that CT calcined at 773 K exhibits a high activity and correlates well with physicochemical characteristics.
