Cobalt-manganese ion-exchanged clinoptilolite supported catalysts for n-hexane oxidation

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 adsorptiondesorption, Fourier transform infrared spectroscopy (FTIR), temperature-programmed reduction (TPR), and Xray photoelectron spectroscopy (XPS). The catalysts were tested in the reaction of complete oxidation of nhexane. 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.

Automated summary

A series of mono- and bi-component cobalt and manganese supported on ion-exchanged clinoptilolite catalysts were prepared and characterized by various techniques. The catalytic activity in the complete oxidation of n-hexane was tested, and the optimal catalyst contained 15% cobalt and 5% manganese oxides, showing the highest activity due to the specific ratio of cation pairs and the presence of Co3O4.
