Figure 4. Relationship between the binding energies (A) Eads(COOH) vs. Eads(CO) and (B) Eads(CHO) vs. Eads(CO) of MoS2 embedded DACs and the transition metal surfaces. The linear proportional relationships between the adsorbents were obtained on Ni, Cu, Ag, Pd, Au, Pt, and Rh surfaces[70]. DACs: Dual atom catalysts.
