The Reactivity of Oxide Surfaces

摘要: Publisher Summary This chapter discusses some of the experimental evidence showing, use isotopes, how lattice oxygen itself takes part in chemisorption step and often catalytic reactions involving oxygen-containing gases including studies isotopic exchange O2, CO, CO2 with a number metallic oxides, together observations upon adsorption these gases. The also heterogeneous catalyzed oxidation CO by O2 decomposition N2O. There are at least two possible effects on catalyst activity: gas may be chemisorbed surface so exercise direct poisoning effect, it slowly incorporated lattice, altering defect structure oxide, thus, effecting intrinsic reactivity catalyst. It appears from 18O extraction results that low pressures primary act N2O determines active sites for each reaction.
