| Abstract: | The valence and coordination state of paramagnetic cobalt atoms in bulk phases of perovskite cobaltate LaCoO3 and cobalt oxide Co3O4 and in nanosized LaCoO3 deposited inside the mesoporous molecular sieve MCM-41 matrix has been studied using ESR. Cobalt(II) cations in deposited cobaltates have octahedral coordination, which is characteristic of perovskite-like structures. |
