Perovskite Type

The electron donor properties of perovskite-type mixed oxides (LaFeO3, PrFeO3, SmFeO3, LaCoO3, PrCoO3, SmCoO3, LaNiO3, PrNiO3 and SmNiO3) were studied based on the adsorption of electron acceptors exhibiting different electron affinity viz. 7,7,8,8-tetracyanoquinodimethane, 2,3,5,6-tetrachloro-1,4-benzoquinone, p-dinitrobenzene, and m-dinitrobenzene. The surface acidity/basicity of the oxides was determined using a set of Hammett indicators. The data were correlated with the catalytic activity of the oxides for the reduction of cyclohexanone with 2-propanol.

Perovskite Type

Perovskite-type LaSrMO4 (M = Mn, Fe, Co, Ni, Cu) mixed oxides were prepared by the decomposition of amorphous citric and ethylenediaminetetraacetic acid complexes and investigated by the XRD, FTIR, BET, TPR, TPD and XPSmethods. Their catalytic behavior in the total oxidation of hexane was examined. The following activity order was found LaSrCoO4 > LaSrNiO4 > LaSrCuO4 > LaSrFeO4 > LaSrMnO4. This is explained in terms of oxygen vacancies and mobile lattice oxygen, particle size and BET surface area. .
