Valence and Coordination State of the Co Atoms in Bulky and Deposited Lanthanum Cobaltates

Abstract

Valence and coordination state of paramegnetic Co (II) atoms in bulk lanthanum cobaltate LaCoO3 with perovskite-like structure and cobalt oxide Co3O4 as well as LaCoO3 nanostructured inside the MCM-41 mesoporous molecular sieve matrix was investigated by ESR technique. Cobalt Co (II) cations in both bulk and nanosized cobaltate phases were found to be in octahedral coordination with oxygen which is characteristic of perovskite-like structures.
