Abstract

Abstract Metal (Ru, Os, Fe) bipyridyl complexes and Ru(NH 3) 3+ 6 were incorporated into several montmorillonite clays and their aluminum and silicon-pillared analogues. Film concentrations and apparent diffusion coefficients were measured and compared by using spectrophotometry, cyclic voltammetry and chronocoulometry. The catalytic role of isomorphously substituted iron was evaluated and implicated by its effects on Ru(bpy) 3+ 3 voltammetric behavior. A model is proposed for charge transport within the novel silicon-pillared clay.
