A work function change study of oxygen adsorption on Pt(111) and Pt(100)

A work function change study of oxygen adsorption on Pt(111) and Pt(100)

Oxygen adsorption on Pt(111) and Pt(100) was investigated using a Kelvin probe to measure adsorbate induced work function changes. The variation of Δφ with θ was linear (p=0.103 D/atom) on Pt(111) even up to θmax∼7×1014 atoms cm−2. On Pt(100), there was an abrupt increase in Δφ at low coverage (...
