Cation-ordered Ce0.5Zr0.4Ti0.1O2 with a high oxygen storage capacity (1310 μmol-O per g at 200 °C) was synthesized via a solution combustion method.
Solution combustion method was adopted for the preparation of ultrafine cerium oxide nanoparticles, which act as excellent photocatalysts for the degradation of dye from aqueous solution.
