Abstract
Pure Fe
2O
3/TiO
2 catalysts (1–35 wt.% Fe
2O
3) and Li-impregnated Fe
2O
3/TiO
2 catalysts (1–10 wt.% Li
2O) were prepared. The structural characteristics of pre-calcined samples were examined by using X-ray diffraction (XRD), thermogravimetric analysis (TGA) and ESR techniques. The surface acidity was measured by the adsorption of
n-butylamine in non-aqueous media. The catalytic conversion of 2-propanol at 320–360 °C using the microcatalytic pulse technique was studied.
XRD of 650 °C-calcination products showed the existence of pure oxide phases as well as other spinels depending on the chemical composition. ESR spectra indicated the existence of Fe(III) in α-Fe
2O
3 phase and in spinel phase. The chemical composition, surface acidity of the catalyst and reaction temperature affect the catalytic conversion of 2-propanol.
