Abstract Superoxide radical ions were observed at the surface of an amorphous silica active in the catalytic ammoximation of cyclohexanone with molecular oxygen. They were generated by the contact of oxygen with a thermally activated sample. The presence of organic radicals on the spent catalyst, which probably played a role in the catalytic process, was also observed.
