2000-07-31: updated summary for ceria-{Y/Gd/La/Mn}

GOAL

Summary for $2000-07-\{04\vert5\vert6\vert 17\}$: the $Ce_{(1-x)}D_xO_{2-\frac{x}{2}},\ 0.1\le{}y\le0.9,\ D=Y,Gd,La,Mn$ system.

Data for the $Ce_{(1-x)}Zr_xO_2$ system, from previous work (Balducci et al. (2000)), are also plotted for comparison.

Results

$Ce^{4+}/Ce^{3+}$ reduction energy

(subscripts are the effective ionic radii of the dopants for 8-coordination, according to Shannon (1976))
