Abstract

Iron(III)-doped zeolites of MFI structure have attracted considerable interest since they are effective catalysts for the oxidation of benzene to phenol by N2O. Unfortunately, the intrepretation of the CW-EPR Fe(III) spectrum of these catalysts is difficult because of poor spectral resolution. (...) An extensive X- and Q-band CW-EPR study between 110 and 390 K has been carried out. A new strategy for the fitting (not simulation!) of these spectra has been envisaged and implemented in computed codes.Next, primary electron spin echo (ESE) amplitudes were recorded at both X- and Q-band. Pseudo-2D ESEEM spectra have been further manipulated in a novel way to obtain Matrix-Proton ESEEM-Induced EPR spectra.(...)
