Abstract

Abstract: Electrochemical behavior of 1,10 phenanthroline complexes of iron and ruthenium, entrapped in MCM-41 mesoporous molecular sieve, was studied. The complexes entrapped had three quasi irreversible redox processes correspondent to those having different coordination number, respectively; the complexes dissolved in aqueous solution had only a reversible redox process. The complexes entrapped could partly be dissociated due to hydroxyls in MCM-41 molecular sieve possessing high activity. The experimental results demonstrated that hydroxyls could act as ligand to coordinate with central ion, meanwhile original complexes were partly dissociated.

Key words: MCM-41 mesoporous molecular sieve, Cyclic voltammetry, Iron and ruthenium complexes
