Two methods for the preparation of Pd/Ce0.5Sn0.5O2 catalysts have been used: solution combustion (SC) of Pd, Ce and Sn precursors mixture, and incipient wetness impregnation by [Pd(NO3)2(H2O)2] solution of Ce0.5Sn0.5O2-δ support, obtained by the SC technique (SC+IWI). The formation of metallic palladium was observed in addition to ionic palladium in a Pdx(Ce0.5Sn0.5)1-xO2-x-δ solid solution due to high-temperature Pd precursor decomposition during the SC process. IWI of Ce0.5Sn0.5O2-δ support has been demonstrated to lead to a uniform solid solution of Pd2+ ions in the Ce0.5Sn0.5O2-δ matrix at 1% Pd content that resulted in high catalyst activity towards CO oxidation. The increase of Pd content to 5% showed no influence on catalytic activity. This observation is explained by the formation of low active PdO species when Pd content is more than 1%. The proposed SC+IWI method allows obtaining highly active Pd/Ce0.5Sn0.5O2 catalysts with low palladium content.
