Abstract

Abstract : The Cover Picture shows the reaction mechanism of two‐electron oxidation of water to form hydrogen peroxide initiated by one‐electron oxidation of a new class of molecular catalysts, aluminum porphyrins, containing the Earth's most abundant metal as the central ion. One‐electron oxidation of an aluminum porphyrin initiates the two‐electron oxidation of water to form hydrogen peroxide as the primary reaction product with the lowest known overpotential (97 mV) and a turnover frequency up to ∼2×10 4 s −1 . The finding thus best fits with the Bauxite mine (Al2 O3 ) and water as the background.
