摘要： 以玻碳电极为基础电极,先用静电自组装方法将带负电荷的四磺酸基苯基铁卟啉和带正电荷的含重氮盐基团的重氮树脂在电极表面进行层-层组装,然后在紫外光的照射下,使铁卟啉的磺酸基与重氮树脂的重氮基引发交联反应,使层与层之间的离子键变成共价键,从而使铁卟啉在电极表面形成稳定、有序、分子水平的层-层构筑.用UV-Vis和IR光谱表征了组装过程,用CV方法研究了该电极的电化学性能.结果表明,该电极不但具有非常优异的稳定性,而且对H2O2的电还原反应也表现出很好的催化活性.

Abstract: Construction of a highly stable covalently attached multilayer film electrode containing iron(Ⅲ) porphyrin was achieved by UV irradiation of ionic self-assembled multilayer films of diazo-resins(DAR) and Fe(Ⅲ) tetrakis(p-sulfonatophenyl) porphyrin(FeTSPP). The fabricated processes of the multilayer film electrode were characterized by UV and IR spectra. The modified electrode has an excellent stability and a good catalytic activity toward electroreduction of H2O2.
