Reaction kinetics and mechanism of oxygen adsorption on the Ni(1 1 0) surface

Initial growth of platinum on oxygen-covered Ni(110) surfaces

“…The first characteristic to note is that the peak positions arising from the NiO(1 1 0) surface throughout the polar angle range are very similar to those from the Ni(1 1 0)-(3 · 1)-O surface. This observation is in contrast with similar published experiments which have suggested the formation of a NiO(1 0 0) film on top of the Ni(1 1 0) substrate [9][10][11]. This is clearly not the case in our investigation, as a shift from a (1 1 0) surface to a (1 0 0) surface would produce large shifts in the peak positions observed in the CAICISS spectrum (as shown in Fig.…”

“…A total exposure of 1.5 L led to the (2 · 1)-O layer being formed on the surface (Fig. 6(c)), previously shown to correspond to an oxygen coverage of 0.5 ML [11,38]. A total exposure of 3.0 L led to the formation of the (3 · 1)-O missing row structure ( Fig.…”

“…[9][10][11][12][13] cover just a few examples). Short exposures to molecular oxygen yield several reconstructions at sub-monolayer coverages.…”

First-principles studies of the oxygen adsorption on unreconstructed and reconstructed Ni(110) surfaces

“…The system of O/Ni(1 1 0) thus has been investigated extensively using a variety of techniques [2][3][4][5][6][7][8][9][10]. The clean surface has a ð1 Â 1Þ structure.…”

Morphology of the interfaces between transition metals and their native oxides: Role of interdiffusion processes

“…Indeed, Ni 3+ is only seldomly observed in oxidation experiments. 18,19,21 This behavior is in contrast to Fe, where the different oxidation states have similar oxidation potentials, and are therefore able to coexist at room temperature. One finally sees that the saturation regime is reached faster for the case of Ni oxidation, and that the total amount of oxygen atoms incorporated in the saturated oxide is 10% smaller compared to Fe.…”
