Abstract: Multicomponent iron-titanium-hafnium oxide materials with different compositions were prepared by combination of homogeneous precipitation with urea and incipient wetness impregnation techniques and tested as catalysts for ethyl acetate oxidation as representative VOCs. Nitrogen physisorption, XRD, Raman, UV-Vis, XPS, Mossbauer spectroscopy and TPR analyses reveal co-existence of substituted FeTi1 - xO2 oxide, finely dispersed iron oxide species with supper paramagnetic behavior and well crystallized alpha-F(e)2O(3) particles, which relative part depends on hafnium content in titania lattice. The effect of phase composition on the catalytic behavior of these materials in ethyl acetate oxidation was discussed. (C) 2016 Elsevier B.V. All rights reserved.
