Abstract: Catalytic supports based on ceria-zirconia binary oxides of various composition are quite frequently used in many laboratory and industrial catalytic applications. High thermal stability, satisfactory surface area and lattice oxygen mobility are main advantages of these materials. In our case three series of CeO2-ZrO2 oxides were used as supports for nickel-containing active phases tested in dry methane reforming (DMR). Three CeO2-ZrO2 materials have been synthesized via different preparation procedures: hydrothermal, Pechini and under supercritical conditions. All synthesized support samples have been in-depth structurally (XRD, RS), texturally (BET, SEM/TEM) and functionally (DRIFT, UV/Vis-DR, XPS) characterized prior to the deposition of nickel precursor. Synthesis-induced changes in both surface and bulk properties of the final CeO2-ZrO2 materials as well as their interaction with the deposited active phase have been studied in the framework of this work. Role of support at designing surface architecture, nanoheterogeneity, specific hydroxylation and affinity toward the deposited oxonickel entities have been discussed in detail.
