过渡金属酞菁配合物化学修饰电极的研究 Ⅰ.对草酸的电催化氧化

STUDIES ON TRANSITION METAL PHTHALOCYANINE CHEMICALLY MODIFIED ELECTRODES I. ELECTROCATALYTIC OXIDATION OF OXALIC ACID

用不可逆吸附法首次制备了Co(Ⅱ)的3,3′,3″,3′″—四硝基酞菁配合物化学修饰电极(CoL CME),用循环伏安法研究了它的电化学性质和电催化功能,与未修饰玻碳电极相比,草酸在CoL CME上的氧化峰电位至少负移300mV,峰电流显著增大,表现出对草酸氧化具有明显的电催化作用,并发现草酸的电催化氧化峰电流与其浓度之间有很好的线性关系。

Cobalt 3,3' ,3',3'''-Tetranitrophthalocyanine chemically modified electrodes (CoL CME) have been prepared for the first time using irreversible adsorption method. The electrocatalytic behavior of the oxidation of oxalic acid at the CoL CME has been studied by cyclic voltammatry. The CoL CME has very strong electrocatalytic effect on the oxidation of oxalic acid. There is a very good linear relationship between the peak current of the electrocatalytic oxidation of oxalic acid and its concentration.
