“…Large amounts of energy are produced via H 2 O 2 exothermic disproportionation into steam H 2 O and O 2 . A newer discovery is that the spontaneous reactions to produce water and oxygen can be harnessed in single‐compartment fuel cells where peroxide is both the fuel, and the oxidant . These energy conversions have long been theoretically postulated to be effective for energy production, storage, and generation – with a thermodynamic cycle theoretically nearly as efficient as H 2 fuel cells .…”

Electrocatalysis for energy‐efficient chemical transformations is a central concept behind sustainable technologies. Numerous efforts focus on synthesizing hydrogen peroxide, a major industrial chemical and potential fuel, using simple and green methods. Electrochemical synthesis of peroxide is a promising route. Herein it is demonstrated that the conducting polymer poly(3,4‐ethylenedioxythiophene), PEDOT, is an efficient and selective heterogeneous catalyst for the direct reduction of oxygen to hydrogen peroxide. While many metallic catalysts are known to generate peroxide, they subsequently catalyze decomposition of peroxide to water. PEDOT electrodes can support continuous generation of high concentrations of peroxide with Faraday efficiency remaining close to 100%. The mechanisms of PEDOT‐catalyzed reduction of O2 to H2O2 using in situ spectroscopic techniques and theoretical calculations, which both corroborate the existence of a chemisorbed reactive intermediate on the polymer chains that kinetically favors the selective reduction reaction to H2O2, are explored. These results offer a viable method for peroxide electrosynthesis and open new possibilities for intrinsic catalytic properties of conducting polymers.

The decaheme cytochrome MtrC from Shewanella oneidensis MR-1 immobilized on an ITO electrode displays unprecedented H2O2 reduction activity. Although MtrC showed lower peroxidase activity in solution compared to horseradish peroxidase, the ten heme cofactors enable excellent electronic communication and a superior activity on the electrode surface. A hierarchical ITO electrode enabled optimal immobilization of MtrC and a high current density of 1 mA cm–2 at 0.4 V vs SHE could be obtained at pH 6.5 (Eonset = 0.72 V). UV–visible and Resonance Raman spectroelectrochemical studies suggest the formation of a high valent iron-oxo species as the catalytic intermediate. Our findings demonstrate the potential of multiheme cytochromes to catalyze technologically relevant reactions and establish MtrC as a new benchmark in biotechnological H2O2 reduction with scope for applications in fuel cells and biosensors.

Hydrogen peroxide, which is a green oxidant and fuel, is produced by a two-electron/two-proton reduction of dioxygen, two-electron/two-proton oxidation of water, or a combination of four-electron/four-proton or/and two-electron/two-proton oxidation of water and two-electron/two-proton reduction of dioxygen. There are many reports on electrocatalysts for selective two-electron/two-proton reduction of dioxygen to produce hydrogen peroxide instead of four-electron/four-proton reduction of dioxygen to produce water. As compared with the two-electron/two-proton reduction of dioxygen to produce hydrogen peroxide, fewer catalysts are known for the selective two-electron/two-proton oxidation of water to produce hydrogen peroxide instead of four-electron/four-proton oxidation of water to evolve dioxygen. Thus, solar-driven production of hydrogen peroxide mainly consists of the catalytic four-electron/four-proton oxidation of water and the catalytic two-electron/two-proton reduction of dioxygen. The overall reaction is the solar-driven oxidation of water by dioxygen to produce hydrogen peroxide. Either or both the four-electron/four-proton or/and the two-electron/two-proton oxidation of water and the two-electron/two-proton reduction of dioxygen requires photocatalysts. The yield of hydrogen peroxide is improved when the compartment for the photocatalytic four-electron/four-proton or/and two-electron/two-proton oxidation of water is separated from that for the catalytic two-electron/two-proton reduction of dioxygen using a two-compartment cell separated by a membrane. The overall solar-driven oxidation of water by dioxygen, which is the greenest oxidant, to produce hydrogen peroxide can be combined with catalytic oxidation of various substrates by hydrogen peroxide.
