“…According to Shpiro et al [55], filling oxygen vacancies and increasing the electron density on the metal leads to a decrease of 16 O 2 / 18 O 2 homoexchange rate. Significant equilibration rates were also obtained by Cunningham et al on RhO x /CeO 2 at ambient temperature [56,57]. In their experiments, active sites for exchange are Rh cations closely associated with cerium oxide:…”

“…It is the facile redox cycle existing between Ce 4+ and Ce 3+ that makes ceria so interesting and it has been studied extensively. Of particular interest has been its reduction 11–15 and oxygen diffusion 16. The defect structure and electrical properties of a single crystal and polycrystalline ceria have also been extensively studied 17–22.…”

“…For instance, benzene, methanol, tetrahydrofuran and benzene have been used as solvents for depositing Pd, Rh and Pt acetylacetonates [210][211][212]. In all these cases, solvent elimination was a required step, followed by a calcination and again a reduction.…”
