基于电化学和原位共振表面X射线散射（RSXS）对Pt沉积电位依赖性的研究，建立了在Au（111）电极表面电化学沉积原子级平整赝晶Pt层的条件。当以相对大的过电位沉积Pt时，在Au（111）表面上形成三维生长的粗糙Pt层。当过电位很小时，Pt核形成，但不再生长。在这两个电位之间的适当的过电位，原子平坦的，赝晶Pt层生长与逐层生长模式。
Conditions for electrochemical deposition of atomically flat, pseudomorphic Pt layer on Au(111) electrode surface were established based on electrochemical and in situ resonance surface X-ray scattering (RSXS) studies on potential dependence of Pt deposition. When Pt was deposited at relatively large overpotential, a three-dimensionally grown rough Pt layer was formed on a Au(111) surface. When the overpotential was very small, Pt nuclei was formed but did not grow any more. At appropriate overpotential between these two potentials, atomically flat, pseudomorphic Pt layer was grown with a layer-by-layer growth mode.
