Key Points

  • To evaluate how tensile strain engineering on atomic-layer platinum supported on intermetallic Pt3Ga affects methanol electrooxidation activity and intermediate binding energetics.
  • Fabricated and tested atomic-layer platinum (AL-Pt) on intermetallic Pt3Ga catalysts in comparison with unstrained Pt counterparts and commercial Pt/C catalysts.
  • Conducted density functional theory (DFT) calculations to model reaction energetics for the methanol oxidation reaction (MOR) and analyze the binding strength of surface intermediates (OH* and CO*).
  • The tensile-strained atomic-layer Pt on Pt3Ga exhibited enhanced electrooxidation performance compared with its unstrained counterpart and commercial Pt/C catalysts.
  • DFT calculations confirmed that the tensile-strained surface is energetically more favorable for MOR, as stronger OH* binding on stretched AL-Pt facilitates the efficient removal of poisoning CO* intermediates.

Abstract

) than those of its unstrained counterpart and commercial Pt/C catalysts. Density functional theory calculations demonstrated that the tensile-strained surface was more energetically favorable for MOR than the unstrained one, and the stronger binding of OH* on stretched AL-Pt enabled the easier removal of CO*.
