Abstract

Series of mono- and bi-component cobalt and manganese supported on ion-exchanged clinoptilolite catalysts were prepared by impregnation method. They were characterized by X-ray diffraction (XRD), N2 adsorption-desorption, Fourier transform infrared spectroscopy (FTIR), temperature-programmed reduction (TPR), and X-ray photoelectron spectroscopy (XPS). The catalysts were tested in the reaction of complete oxidation of n-hexane. The highest catalytic activity was shown by the two-component catalyst containing 15 % of cobalt and 5 % of manganese oxides, which is due to the optimal ratio between the cation pairs Co2+/Co3+ and Mn3+/Mn4+ at Co/Mn = 1 on the surface calculated from XPS data and the presence of Co3O4.
