Abstract. Imlay and Linn show that exposure of logarithmically growing Escherichia coli to hydrogen peroxide (H 2 O 2) leads to two kinetically distinguishable modes of cell killing.Mode one killing is pronounced near 1 mM concentration of H 2 O 2 and is caused by DNA damage, whereas mode-two killing requires higher concentration (> 10 mM).The second mode seems

Provided by the Springer Nature SharedIt content-sharing initiative The direct utilization of solar energy for the artificial photosynthesis of hydrogen peroxide (H2O2) provides a reliable approach for producing this high-value green oxidant.
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.
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 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.
Hydrogen peroxide (H 2 O 2), as a value-added chemical, can be produced by a two-electron reaction in the process of water cracking in photochemical cells, and this reaction has a competitive relationship with the four-electron reaction of oxygen.
