In this paper we describe the use of electrogenerated silver particles within a Y zeolite-encapsulated iron-SALEN [SALEN = N,N’-bis(salicylaldehyde)ethylenediimine] complex to facilitate electron transfer reactions. The increase in the electrochemical accessibility of the zeolite-encapsulated complexes by introducing a dispersion of small metallic particles within and on the external surface of the microporous system is effective and encouraging. Additionally, the possibility of viable electrocatalysis by zeolite "ship-in-a-bottle" complexes has been dramatically improved. The influence of the potential scan rate on the enhancement of the electroactivity of the entrapped complex and on its stability is also discussed.
