the HER activity also increases initially (left side of the volcano plot, Fig.4e). Under the electrochemical condition, the charge of the metal plays a decisive role with regard to water dissociation58,59. Choi’s group reported the counterintuitive promoting effect of CO molecule on alkaline HE...
Using optPBE-vdW, we calculate the binding energy of CO to these alloys to be −30.8 kcal/mol for Pt/Cu(111) and −24.2 kcal/mol for Pd/Cu(111) at a coverage of 0.01442 molecules/Å2, respectively. A Bader charge analysis shows that the CO adsorbate molecule accumulates ...
