Abstract
Thermal and photo-induced generation of radicals during adsorption of m-dinitrobenzene (m-DNB) on donor centers (D(S)) of gamma-Al2O3 from v arious solvents has been studied. Energy characteristics of these proc esses are shown to be significantly dependent on the ionization potent ial (I(p)) of solvent molecules (D). A mechanism for these processes i s suggested implying the formation of surface electron donor-acceptor (EDA) complexes of the type [D-NB-D(S)] with the participation of solv ent molecules.
