摘要: 用循环伏安法研究MCM-41分子筛修饰电极对铁(Ⅱ)和钌(Ⅱ)的1,10-氮杂菲配合物的电化学行为.由于MCM-41中孔分子筛孔表面存在非常活泼的羟基,使其具有很高的活性,它能使分子筛本身作为配体与金属离子配位,并使原来的配体部分解离.

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
