Abstract:
The adsorption of nitroxyl radicals TEMPON and m-dinitrobenzene (m-DNB) molecules on the donor and aceptor centers of γ-Al2O3 has been studied. It is shown that ESR spectra of adsorbed TEMPON radicals at 100–300 K could be accounted for by the slow motions of these radicals (τcorr=1x10-7 ∼ 1.5x10-8s). The adsorption of m-dinitrobenzene on donor centers is accompanied by the appearance of radicals with similar ESR spectra. These particles are also assumed to be stabilized on the surface as nitroxyl radicals. A mechanism for their formation is suggested.
