Fundamental and applied research on the aqueous sulfide/polysulfide redox couple has been carried out, motivated by its possible use in photoelectrochemical cells (PECs) and redox batteries. Recent work on PECs has concentrated on the reactions at photoelectrodes. Much less attention has been given to the development of efficient redox electrodes which can be used as a counterelectrode in a PEC or as an electrode in a redox cell. Objectives of the present work are to obtain information on the electrochemical and chemical reactions of the aqueous sulfide/polysulfide redox couple and to use that information to design a stable and efficient redox electrode.
