Spectroscopic determination of metal redox and segregation effects during CO and CO/NO oxidation over silica-supported Pd and PdCu catalysts

Site requirements for inhibition-free CO oxidation over silica-supported bimetallic PdCu alloys

“…In our recent work, 17,18 we demonstrated experimentally that PdCu catalysts outperform their monometallic Pd counterparts, in terms of both CO oxidation activity and NO inhibition. We attributed these effects to the electronic exchange of Cu and Pd, as well as the mobility of Cu from the bulk to the surface upon light-off, which offers a binding site for O 2 to adsorb and react.…”
