SnO{sub 2} electrodes modified with a 2-4 monolayer thick coating of complex organic silicon and nitrogen compounds bind a single dense layer of zeolite Y particles, presumably via siloxane linkages. The cationic silane and zeolite particles provide ion binding sites for multiply charged anions such as Fe(CN){sub 6}{sup 4{minus}1}, large cations such as tris(2,2'-bipyridyl)osmium(II) and tris(1,10-phenanthroline)iron(II), and small cations such as trimethyl(ferrocenylmethyl)ammonium. Cyclic voltammetric data are consistent with occupation of sites within the zeolite framework by the small cations, occupation of zeolite outer surface sites by the large cations, and occupation of sites in the silane film by Fe(CN){sub 6}{sup 4{minus}1}. The large cations situated on the zeolite outer surface are found to mediate all electron transfers to and from the smaller cations contained in the bulk. 6 figures, 12 references.
