Fig. 1: Optimized structural models and calculated migration energies of Cu0.3Co2.7O4 and Ir1/Cu0.3Co2.7O4.
From: Distance effect of single atoms on stability of cobalt oxide catalysts for acidic oxygen evolution
a Optimized structural model of Cu0.3Co2.7O4. Red, blue, and brown spheres represent O, Co, and Cu atoms, respectively. b Calculated migration energies of Co atoms on Cu0.3Co2.7O4. Pink spheres represent migrated Co atoms. c Optimized structural model of Ir1/Cu0.3Co2.7O4. Green spheres represent the Ir atom. Pink and blue circles represented the Co site located at different distances from the Ir atom. d Calculated migration energies of Co atoms at different sites.
