电催化是化学修饰电极研究的中心课题之一，血红素是一种重要的铁卟啉化合物，其中的铁原子能够以两种价态存在．我们采用循环伏安法将血红素修饰于电极表面，得到了氧化还原体（ｒｅｄｏｘ）型化学修饰电极，并用于儿茶酚类化合物和抗坏血酸的电催化氧化研究．采用伏安法... Electrocatalysis is one of the central topics in the study of chemically modified electrodes. Heme is an important iron porphyrin compound in which iron atoms can exist in two valence states. We modified the hemoglobin on the electrode surface by cyclic voltammetry, and obtained a redox-type chemically modified electrode, which was applied to the electrocatalytic oxidation of catechols and ascorbic acid. Using voltammetry ...
