摘要
Density functional calculations are used to study the adsorption of O atoms and O-2 molecules on boron-doped graphite models. The presence of substitutional boron increases the binding energy with atomic oxygen. The formation of strong B-O bonds makes the structure of the small clusters obviously distorted. In contrast, the O-2 molecule is found to only slightly physisorbs and very little charge transfer occurs. The theoretical results are compared to existing experimental ones. (C) 2004 Elsevier B.V.
