Understanding the atomistic behavior of small molecules (O2 and N2) on monometallic M13 nanoparticles
Both experimental data and density functional theory (DFT) calculations clearly indicate that the reactivity of metal clusters for NO is determined by the energy and orbital type (4d or 5s) of the valence band top. Here, we explore this correlation for the reactivity of M13 nanoclusters, being M = A...

Summary: | Both experimental data and density functional theory (DFT) calculations clearly indicate that the reactivity of metal clusters for NO is determined by the energy and orbital type (4d or 5s) of the valence band top. Here, we explore this correlation for the reactivity of M13 nanoclusters, being M = Ag, Au, Co, Cu, Fe, Ir, Ni, Os, Pd, Pt, Rh and Ru and adsorbed diatomic molecules, O2 or N2. The possible adsorption configurations, interatomic distances, and adsorption energies for O2 and N2 on M13 clusters have been analyzed in detail.
[Display omitted]
•Transition metal clusters show varying reactivity for O2 and N2 adsorption.•Adsorption energies decrease with increasing atomic number of metal elements.•Correlation between adsorption energies and molecular bond lengths observed.•Potential catalysts for oxygen and nitrogen dissociation identified.•Adsorption of O2 on nanoparticles may be up to 2.3 eV more stable than N2. |
