Calcination Temperature. Calcination temperature had strong influence on the physicochemical characteristics: its increase from 500°C to 800°C increased the solid-solution particle size (5.6–12.4nm) and decreased the SSA (186–45m2g−1), the relative amounts of Ce3+ and Mn4+ oxidation states, the reducibility, and, as a consequence of all the above, the catalytic activity.
