摘要
用自组装技术以ω-巯基己酸(6-MHA)对金电极进行修饰。通过表面增强拉曼散射(SERS)光谱和电化学方法研究了6-MHA自组装单分子膜(SAM)在金电极表面的形成及由此引起的电极双电层电容的变化,并研究了该自组装单分子膜的结构模型及修饰电极对叶绿素的催化性能。结果表明,6-MHA在金电极表面能够形成一层稳定的自组装膜,并对叶绿素的氧化还原过程具有明显的催化作用。
ω Mercaptohexanoic acid (6 MHA) self assemble modified gold electrode has been made by the authors.The SERS spectrum and the variations of double layer capacitance( C d )which occurred in the formation of 6 MHA self assembled monolayers(SAM)on gold electrode surface were studied.The structure model of this SAM was deduced.The results show that 6 MHA can form stable SAM on gold electrode,and this 6 MHA SAM electrode has obvious catalysis for the redox reaction of chlorophylls.
