Abstract:
The total neighbors lost by adjacent atoms composing an adsorption site as compared with bulk atom are considered as a measure of local surface imperfection. Semi-empirical calculations have shown that surface defects provide the formation of weakly bound, but very inclined to hydrogenation state of atomic nitrogen that makes the grain boundary to be the center for sustained surface wave nucleation during NO+H2 reaction on the Rh twin tip. In the same terms, an optimal site for catalytic NH3 synthesis consisted of 2 and 3 Ru atoms is presumably characterized by 12 and 1 lost neighbors, respectively, whereas Rh is a poor catalyst in any case. The same approach can be applied to any other adsorption or catalytic processes exhibiting high surface sensitivity.
