Abstract: A modified sol–gel method was used as a novel approach to the synthesis of nickel–praseodymium catalysts supported on LaFeO₃/SiO₂. The catalysts were investigated using XRD, EDX, low-temperature nitrogen physisorption, Mössbauer spectroscopy, TPR and XPS; oxygen mobility in the samples was studied using the oxygen isotope exchange method; then the catalysts were tested in the ethanol steam reforming reaction. The effect of synthesis conditions on catalyst properties was analyzed, and it was found that higher oxygen mobility provides higher resistance to coke formation.

Keywords: cyclodextrins, sol–gel method, perovskites, apatite-type lanthanum silicate, ethanol steam reforming, supported catalyst.
