Perovskite oxides, with an ABO3 general formula, have attracted much attention as effective peroxymonosulfate (PMS) activators because of their composition adjustability and chemical stability. A doping strategy has been applied to enhance the PMS activation capability modulation crystal structure parent LaCoO3-δ perovskite by substituting Co atoms located at B-site, high valence state transiti...

We have developed the crystal-field approach with strong electron correlations, extended to the Quantum Atomistic Solid-State theory (QUASST), as a physically relevant theoretical model for the description of electronic and magnetic properties of 3d-atom compounds. Its applicability has been illustrated for LaCoO3, FeBr2 and Na2V3O7. According to the QUASST theory in compounds containing open 3...

A family of Ce-doped LaCoO 3 perovskites are presented as possible catalysts for Cl–VOCs elimination. These materials with different contents Ce were obtained through the citrate and reactive grinding methods. The insertion in original perovskite structure favours presence Co 2+ /Co 3+ /Ce 4+ redox pairs a higher content oxygen vacancies that enhances catalytic performance chlorobenzene combust...

Cobalt-containing metal oxides [perovskites (LaCoO(3), NdCoO(3), YCoO(3), La(0.7)Sr(0.3)CoO(3)), spinel (Co(3)O(4)) and wolframite (CoWO(4))] have been examined as catalysts for photocatalytic water oxidation with Na(2)S(2)O(8) and [Ru(bpy)(3)](2+) as an electron acceptor and a photosensitizer, respectively. Catalysts with the perovskite structure exhibited higher catalytic activity as compared...
