Kinetics of the reaction of oxygen with clean nickel single crystal surfaces

Chapter 2 The Development of Basic Concepts of Chemical Kinetics in Heterogeneous Catalysis

“…Phase transformations in heterogeneous catalysis have been described recently Ьу topochemical kinetic models [111][112][113][114][115]. These models were taken from solid chemistry, where they had been developed for "gas-solid" геас tions.…”

“…А simple topochemical model for the growth of NiO islands оп the Ni surface during the reaction of oxygen with а Ni(1l1) crystal is clearly described Ьу Holloway and Hudson [112]. They considered three cases in which the rate-determining step is, respectively (а) oxygen sorption from the gas phase (surface diffusion is fast), (Ь) surface diffusion of oxygen, and (с) oxygen insertion over the island boundary.…”

“…ТЬе topochemical model [112] suggests that an island сап Ьауе n oxide layers. Apparently, this model сап Ье applied in the саве of the chemisorbed two-dimensional рЬаве growth, ав had been done Ьу Boreskov et al [116].…”

“…Опе such model was соп sidered in the description of а topochemical model [112]. А correct mathematical description ofmulticomponent diffusion processes in solids obtained оп the basis of irreversible process thermodynamics сап Ье found in refs.…”

X-ray photoelectron diffraction and low-energy electron diffraction study of the interaction of oxygen with the Ni(001) surface: c(2 × 2) to saturated oxide

“…These two co-existent oxide phases were flrst discussed by Holloway and Hudson [3] and . flrst hypothesized to be Ni0(001) and NiO(lll) by Mitchell et al [ 4].…”
