A molecular approach for designing nanophase Ce{sub 1-x}M{sub x}O{sub 2-{delta}} based catalysts efficient for redox gas reactions, such as emission control, is presented. Oxygen vacancies in solid solutions of doped CeO{sub 2} can be designed to achieve a more active catalyst for the reaction of SO{sub 2} and CO to produce S and CO{sub 2}. Ca-doping lowers the light-off temperature for the reaction by some 70{degrees}C. By tailoring the properties of oxygen vacancies, such as sizes, chemical moieties, and binding energies it is possible to improve the catalytic activity of the catalyst.
