Identification of Active Oxygen Species over Fe Complexes in Zeolites,analyzed. Particular attention is paid to a recently discovered oxygen species O. formed upon N.O decomposition over Fe complexes in zeolites. High reactivity of α-oxygen coupled with the high concentration allow to reliably identify its participation in the oxidation of methane to methanol and benz

Catalysis Using Guest Single and Mixed Oxides in Host Zeolite Matrices,ibility to (i) stabilize (mixed) oxide nanoparticles with unusual catalytic properties, (ii) combine sorption characteristics of the microporous material with the reactivity characteristics of the oxide, (iii) have synergetic interactions between isolated and multinuclear metal-oxide species and (iv

Reactivity Theory of Zinc Cation Species in Zeolites,ng ab initio methods. We studied the relation between stability of a site and its catalytic activity. In addition to cationic positions formed by a zeolitic ring with two Al ions, the sites with distantly placed aluminiums were also studied. It was shown that the latter tend to form oxygen bridged z

, Simulation of Cu-Species in Zeolites: Siting, Coordination, UV-Vis Spectra and Reactivity, systems is discussed. The latter are able to discriminate between different types of sites in a given framework and between different frameworks. Two types of Cu. sites are identified. Type I sites are found at the channel walls with Cu. coordinated to 3 – 4 oxygen atoms of a five- or six-membered

Asymmetric Oxidation of Sulphide on Metal Ion Planted in Mesoporous MCM-41,llapse of the mesoporous structure of MCM-41 was observed after the TIE treatment. The cations of Al, Ti, Cr, Mn, Zn, or Zr could be incorporated in MCM-41 with high dispersion, while Fe, Co, Ni, Cu, Ga, Pd, or Pt formed nano-scale particles on the outside of the MCM-41 particles. The reaction mecha

Photocatalysis of Cations Incorporated within Zeolites, performance for the decomposition of NOx (NO, N.O) into N. and O. at 275 K. In-situ ESR, UV-VIS, photoluminescence and XAFS (XANES and FT-EXAFS) investigations revealed that the transition metal ions exist in a highly dispersed state with a linear 2-coordination sphere within the pores of the ZSM-5
