Fig. (c) displays the influence of the SA on the E CO 2 ads and ∆d C-O max . For this analysis, we focus on bridge sites of SAAs with the Pd host and corresponding to the surfaces (111), (100), (110), and (211). Firstly, we note that the presence of the SA typically favors the CO 2 chemisorption compared to the case of monometallic surfaces. Moreover, we observe a decrease in the E ads as the group of the SA increases within a given period in the periodic table. For instance, the average E ads decrease between Ru and Rh bridge sites in Fig. ) is 0.104 eV. In general, ∆d C-O max seems to be mostly dictated by the SA element. Variations in the C-O elongation among the different surface terminations are small and do not show a clear pattern. The analysis for bridge sites of SAAs based on Cu and Zn hosts (see ESI Section 2.4) highlights similar trends to those for SAAs based on the Pd host.
