Abstract

Density functional theory and slab models are used to study the effects of CO on the configuration of Mo/Au(1 1 1) interfaces. In the absence of CO, the theoretical calculations show site exchange or intermixing after depositing Mo atoms on Au(1 1 1). The presence of CO prevents Mo-Au intermixing and, thus, enhances the mobility of Mo on the surface. This phenomenon can explain a novel growth mode found when using Mo(CO)₆ as a precursor for the preparation of metal nanoparticles on Au(1 1 1).
