Resumen:
Supported MnCuCe and MnCe mixed oxides
catalysts were prepared and evaluated in n-hexane combustion
reaction. They presented an excellent catalytic
activity in total combustion of n-hexane. Catalysts were
characterized by means of XRD, XPS, SBET and TPR
techniques. The addition of Cu did not enhance the catalytic
activity of MnOx/Al2O3 due to the formation of the
complete Mn2CuO4 spinel. The presence of cerium favored
the formation of manganese oxide species with low crystallinity,
with high oxygen mobility and high oxygen
vacancies. A higher content of Ce was necessary to obtain
catalysts with higher oxidation state of Mn and Ce species.
