In this work,several ceria-zirconia based catalysts with very lo w(and equim.lar) m.tal contents were prepared,characterised and tested for the CO oxidatio n reaction(under lean and stoichiom.tric conditions),trying.to em.late those conditions found in a diesel oxidation catalyst(DOC) system.from.a diesel eng.ne and those encountered under g.soline exhaust(λ=1).The m.tals chosen are Cu,Co,Ag.and Pt(as a reliable benchm.rk).The results reveal enorm.us differences am.ng.reducibility and catalytic activity despite quite sim.lar structural and textural properties of the catalysts,showing.differences am.ng.dispersion(Ag.catalyst seem. to present a low level of dispersion).This catalyst seem. to be characterised,as well,by a strong.electronic interaction between Ce and Ag.centres which is sug.ested to yield an im.roved reducibility under H_(2)-TPR ***,the order in catalytic activity(Cu>Ag.Co≈Pt>>support) seem. not to follow the order found in reducibility and the Cu-catalyst seem. to be the m.st active independently on the reaction conditions,yielding.nearly overlapped CO oxidation catalytic *** resting.y,a stro ng.correlation between the catalytic activity under the two conditions tested and the OSC values of the Ce_(0.8)Zr_(0.2)O_(2)-supported m.tal catalysts is ***,OSC param.ter m.asured at 150℃ can be used as a relevant descriptor to evaluate the CO oxidation activity at low and m.dium.conversions for the investig.ted catalysts,m.ch better than the H_(2)-TPR m.asurem.nts.
