Hydrogen spillover from NiO to the large surface area CeO2-ZrO2 solid solutions and activity of the NiO/CeO2-ZrO2 catalysts for partial oxidation of methane

摘要: Reduction behaviors of NiO-modified large surface area CeO2–ZrO2 solid solutions were examined by the temperature-programmed reduction technique. NiO modification solution lowered temperature solution. At stage solution, was sole species observed XRD. Therefore, particles apparently facilitated lowering its temperature. The activity NiO/CeO2– ZrO2 catalysts for partial oxidation methane to H2 and CO increased with an increase oxygen storage capacity solutions. having strong interaction support showed high stability methane, while weak produced a amount coke (carbon nanotubes).
