We explore the feasibility of using hydrogen to probe local surface reactivity. To do this, we compare the dissociation dynamics of H 2/Cu3Pt(111)[12̄1] and H2/NiAl(110) [11̄0]. Calculation results show that the corresponding adsorption/sticking probability S vs. incidence translational energy Et pr...
