NiCo-Gd0.1Ti0.1Zr0.1Ce0.7O2 catalyst for dry reforming and partial oxidation of methane: effect of NiCo applying method on the conversion of methane to synthesis gas.

[Display omitted] A series of catalysts based on mesoporous ceria solid solutions containing NiCo active component was synthesized via co- precipitation, impregnation, hydrothermal and core–shell (sol–gel) methods and applied to partial oxidation and dry reforming of methane. In the co-precipitated and impregnated catalysts, a better NiCo dispersion and a stronger interaction between NiCo species and the ceria- based support in comparison with other catalysts were observed, which affected activity and selectivity. Thus, simpler methods of applying the active component were more advantageous owing to the manifestation of strong metal–support interactions. [ABSTRACT FROM AUTHOR]
