Substrate oxidation enhances the electrochemical production of hydrogen peroxide.

ABSTRACT: Hydrogen peroxide (H₂O₂) is electrochemically produced via oxygen (O₂) reduction on a carbon cathode surface. In order to enhance the production of H₂O₂, anodic loss pathways, which significantly reduce the overall H₂O₂ production rate, should be inhibited. In this study, we investigate the effects of organic electron donors (i.e., typical chemical contaminants) on the anodic loss pathways of H₂O₂ in a single-cell electrochemical reactor that employs an anode composed of TiO₂ over-coated on a mixed-metal oxide ohmic contact catalyst, Ir_0.7Ta_0.3O₂, deposited on a Ti-metal that is coupled with a graphite rod cathode in a sodium sulfate (Na
