Ei. Latkin et al., The role of subsurface oxygen in oscillatory behaviour of CO+O-2 reaction over Pd metal catalysts: Monte Carlo model, J MOL CAT A, 158(1), 2000, pp. 161-166
The statistical lattice model constructed for (CO + O-2)/Pd reaction takes
into account the change of surface properties due to the penetration of the
adsorbed oxygen into subsurface layer. The model demonstrates the oscillat
ions of the rate of CO2 formation and the concentrations of the adsorbed sp
ecies. Autowave processes on the model palladium surface accompany these os
cillations. The existence of the reaction zone between the moving adsorbate
islands characterised by the elevated concentration of the free active cen
tres has been shown. The results obtained make it possible to interpret the
surface processes on the atomic scale. (C) 2000 Elsevier Science B.V. All
