Hydrogen peroxide (H2O2), which is used as a fuel in H2O2 fuel cells,1 is produced by two-electron/two-proton reduction of dioxygen (O2), two-electron/two-proton oxidation of water ( H2O), or combination of four-electron/four-proton or/and two-electron/two-proton oxidation of H2O and two-electron/two-proton reduction of O2.2 This lecture focuses on solar-driven production of H2O2 from H2O and O2 in the air and its usage in green oxidation reactions.2 H2O2 is produced by combination of the four-electron/four-proton oxidation of H2O oxidation and the photocatalytic two-electron/two-proton reduction of O2 using H2O oxidation catalysts and O2 reduction photocatalysts.3-5 The yield of H2O2 is improved when the compartment for the photocatalytic four-electron/four-proton or/and two-electron/two-proton oxidation of water with a semiconductor photocatalyst (WO3 or BiVO4) is separated from that for the catalytic two-electron/two-proton reduction of O2 with a cobalt(II) chlorin complex [CoII(Ch)] using the two-compartment cell separated by a Nafion membrane.6,7 The overall solar-driven oxidation of H2O by O2 to produce H2O2 is combined with catalytic oxidation of benzene by H2O2 to produce phenol, when the overall reaction is solar-driven hydroxylation of benzene by O2, which is the greenest oxidant, with H2O.8,9
