The photoreduction of methylviologen via electron transfer from aluminosilicate zeolites

Autor: Larry Kevan, Christophf Finel, Hugh J. D. McManus

Publikováno v: Radiation Physics and Chemistry. 45:761-764

The photoreduction yields of methylviologen and various alkylated homologues in zeolite-X, Y and A were determined at 77 K in the absence of any reducing counteranion. Upon irradiation at 77K, dehydrated samples turned light blue and a single line ES
