Abstract
Manganese mixed oxides were synthesized by self-combustion and co-precipitation, maintaining constant the relationship Mn2 + / Mg2 + = 1 and M2 + / M3 + = 3, which are characteristic of the oxides obtained by thermal decomposition of hydrotalcite-like precursors. The catalysts were characterized using X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption, and temperature- programmed reduction, and they were evaluated in the catalytic oxidation of 2 -propanol. The results showed that the use of such self-combustion synthesis method allows generating oxides with structural, textural, redox and catalytic properties similar to those obtained for the oxide prepared via a hydrotalcite-like precursor. The catalytic performance of mixed oxides was directly related to their redox properties. We evaluated the manganese oxide obtained by self-combustion deposited on Fecralloy metal monoliths, as well as the effect of the adhesion of the active phase of the precoat materials using colloidal alumina. The oxidation of 2-propanol over the monolith showed that there is no loss of activity when a catalyst is on a structured material.References
