摘要
The influence of the order of an oxygen adlayer on Pt(111) on the adsorption of D2 has been investigated using a combination of He diffraction and reactive scattering techniques. A close correlation was found between the onset of the order/disorder phase transition of the p(2 x 2)O structure and an increase of the D2 sticking probability. A detailed analysis shows that the adsorption process responsible for this phenomenon is nonactivated and that it is sensitive to local order on a scale of 4-7 atoms. An explanation is proposed which considers the influence of the local symmetry on the dynamics of the adsorption process.
