Abstract: This article describes the capabilities of coupled UHV-electrochemistry as a means to obtain the microscopic information of the electrode-solution interface. It presents the experimental aspects for sample preparation and surface analytical techniques and some selected studies of the recent results with single-crystal electrode surfaces; the phase transition for the reconstructed Au(100)-hex and Pt(100)-hex electrodes in the electrochemical cell and the structural study of the epitaxial growth of Pt on Ru(0001) and Ru(1010) surfaces as well as the growth of RuO2(100) on Ru(0001).
