Infrared Spectroelectrochemical Study of Cyanide Adsorption and Reactions at Platinum Electrodes in Aqueous Perchlorate Electrolyte

Abstract

In situ infrared (IR) spectroelectrochemistry is used to investigate the behavior of cyanide (CN) at polycrystalline platinum surfaces in aqueous perchlorate (CLO4(-) electrolyte, IR spectroelectrochemical data reveal the existence of a number of surface, as well as solution, cyanide species in the interfacial region. Within the double-layer potential region, there is IR evidence for several forms of absorbed cyanide. When the potential is made sufficiently positive, cyanide is oxidized to form cyanate. Other solution cyanide species which may be formed at the platinum-cyanide solution interface include hydrogen cyanide and square planar platinum cyanide complex.
