Surface strain-regulated interfacial catalysis in Pd 3 Pb nanosheets for enhanced C1-pathway ethanol electrooxidation

Pb(311) surface-which upshifts the d-band center to -1.53 eV and strengthens *OH binding (-3.29 eV), thereby optimizing intermediate adsorption energetics and facilitating the oxidative removal of carbonaceous poisons. This work provides a synthetic route to engineer crumpled surface topography in intermetallic nanosheets and demonstrates its critical role in regulating interfacial catalysis for C1-selective alcohol electrooxidation.
