Bimetallic Supported Pd-Ag Catalysts

Abstract:

Series of Pd-Ag/SiO₂, Pd/CeO₂ and Pd-Ag/CeO₂ catalysts with different Pd/Ag ration were synthesized and investigated. It was shown that simultaneous reduction of Pd and Ag took place for Pd-Ag/SiO₂ and Pd Ag/CeO₂ catalysts during TPR-H₂. That may be associated with formation of bimetallic Pd-Ag particles. The high temperature of Pd reduction was observed for Pd/CeO₂ and Pd-Ag/CeO₂ catalysts. That was associated with strong interaction of PdO with CeO₂ or formation of mixed Pd_xCeO_2-δ phase.
