Abstract

The formation of radicals on the surface of alkaline-earth oxides, Al2O3 and SiO2-Al2O3, has been studied by ESR. The following molecules have been used: nitrobenzene, perylene, anthracene, naphthalene and hexamethylbenzene. The concentration of electrondonor sites increases with increasing Lewis base-strength of the oxides. The concentration of electron-acceptor sites increases with increasing Lewis acid-strength.

The nature of electron donor-acceptor sites and the relation between these and Lewis base-acid sites is discussed.
