Dioxygen dissociation over man-made system at room temperature to form the active α-oxygen for methane oxidation
Original language description
Activation of dioxygen attracts enormous attention due to its potential for utilization of methane and applicationsnin other selective oxidation reactions. We report a cleavage of dioxygen at room temperature over distant binuclearnFe(II) species stabilized in an aluminosilicate matrix. A pair of formed distant -oxygen species [i.e., (Fe(IV)═O)2+]nexhibits unique oxidation properties reflected in an outstanding activity in the oxidation of methane to methanolnat room temperature. Designing a man-made system that mimicks the enzyme functionality in the dioxygen activationnusing both a different mechanism and structure of the active site represents a breakthrough in catalysis.nOur system has an enormous practical importance as a potential industrial catalyst for methane utilization becausen(i) the Fe(II)/Fe(IV) cycle is reversible, (ii) the active Fe centers are stable under the reaction conditions, and (iii)nmethanol can be released to gas phase without the necessity of water or water-organic medium extraction.
