Description

<p>In situ scanning tunneling microscopy (STM) was employed to examine the interfacial structure of a well-defined Ir (111) electrode in an alkaline solution containing NaCN. The STM images disclosed the ordered structure of a CN adlayer to be (2√3 × 2√3)R30°. The adlayer structure consists of 6-membered-ring unit cells of CN, which is the same as that previously found on Pt(111). The replacement of protons or hydronium cations with Na+ was proposed to take place at the center of the CN rings at positive potentials.</p>
