A method for promoting the supported catalysts using noble metal nanoparticles. Different noble metal precursors are preferentially deposited onto the supported metal catalysts through Chemical vapor deposition (CVD), and compositions so produced. Further, the promoted catalyst is used for CO and CO.sub.2 hydrogenation reactions, increasing the reaction conversion, C.sub.5+ compounds selectivity and chain growth probability. The active phase of catalyst can be either cobalt oxide, nickel oxide or their reduced format (Co.sup.0 or Ni.sup.0), and the noble metal is preferably Ruthenium.

A core-shell oxide material comprises: a core which comprises a ceria-zirconia based solid solution powder having at least one ordered phase of a pyrochlore phase and a phase; and a shell which comprises an alumina based oxide disposed on at least a portion of a surface of the core.

The present disclosure relates to zero-PGM (ZPGM) catalysts including variations of Nickel-doped Copper-Manganese spinel for improved catalyst performance at the stoichiometric condition for use within three-way catalyst (TWC) applications. The ZPGM catalyst material compositions within the aforementioned ZPGM catalysts are expressed with general formulas of Cu.sub.1-XNi.sub.XMn.sub.2O.sub.4 (A-site substitution) and Cu.sub.1Mn.sub.2-XNi.sub.XO.sub.4 (B-site substitution). The ZPGM catalysts are subjected to a TWC isothermal steady-state sweep test to assess the catalytic performance (e.g., NO conversion). Test results indicate the ZPGM catalysts exhibit higher NO conversions, at stoichiometric condition and lean conditions, when Ni substituted the B-site cation of the CuMn spinel as compared to Ni substituted the A-site cation of the CuMn spinel. Additionally, NO conversions of the ZPGM catalysts are significantly affected, at the stoichiometric condition, by the molar ratio of the Ni dopant within the A or B-site cation of the CuMn spinel.
