Abstract:
Based on the Sabatier principle, it is widely accepted that the ORR activity is decisively controlled by the adsorption energies of the reaction intermediates. Weakening the *OH adsorption energy by ~0.1-0.15 eV with respect to Pt(111) improves the ORR activity, which has been shown by various experimental [1] and theoretical [2] studies. Recently, Calle-Vallejo et al. have extended the geometrical concept of coordination numbers to second nearest neighors, which reveals fundamental design prin...     »
