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．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.
