in other selective oxidation reactions. We report a cleavage of dioxygen at room temperature over distant binuclear
Fe(II) species stabilized in an aluminosilicate matrix. A pair of formed distant -oxygen species [i.e., (Fe(IV)═O)2+]
exhibits unique oxidation properties reflected in an outstanding activity in the oxidation of methane to methanol
at room temperature. Designing a man-made system that mimicks the enzyme functionality in the dioxygen activation
using both a different mechanism and structure of the active site represents a breakthrough in catalysis.
Our system has an enormous practical importance as a potential industrial catalyst for methane utilization because
(i) the Fe(II)/Fe(IV) cycle is reversible, (ii) the active Fe centers are stable under the reaction conditions, and (iii)
methanol can be released to gas phase without the necessity of water or water-organic medium extraction.Pracoviště Ústav fyzikální chemie J.Heyrovského Kontakt Michaela Knapová, michaela.knapova@jh-inst.cas.cz, Tel.: 266 053 196 Rok sběru 2021 Elektronická adresa http://hdl.handle.net/11104/0308778
