Issue Date: | 2018 | Part of: | Journal of chemical physics letters | Volume: | 703 | Start page: | 94 | End page: | 96 | Abstract: | Ag2+(b) species were detected by electron paramagnetic resonance (EPR) on silver loaded over ceria by impregnation in a previous work. Contrasting the EPR simulation with the experimental measurements evidenced that, upon propene oxidation, the Ag2+(b) species transform into two clusters each containing 2 Ag2+ and 1 Ag+ species. This cluster is composed of two parallel electron spins (dimer) and three nuclear spins (trimer). Such a result led us to suggest that initially, Ag2+(b) species clusters were formed by three parallel electron spins. The ferromagnetic character of Ag2+(b) species may explain their catalytic performance towards total oxidation of propylene. |
