摘要：

Photostimulated formation of stabilized benzene cation-radicals over ZSM-5 zeolite has been found. Benzene ionization follows a monophotonic mechanism starting from photon energy hv = 2.8 eV. The formation of donor-acceptor complexes of adsorbed benzene molecules with strong accepting sites on zeolite is suggested. Irradiation within the charge-transfer band is accompanied by photodissociation of these complexes and generation of benzene cation radicals.
