【摘要】 通过紫外-可见光谱跟踪研究了四磺酸基酞菁钆/重氮树脂DAR/GdTs2薄膜的自组装过程,利用原子力显微镜(AFM)表征了自组装薄膜的形貌,制备了(DAR/GdTs(Pc)2)修饰玻碳电极,应用循环伏安法测试了(DAR/GdTs(Pc)2)修饰玻碳电极对抗坏血酸的电催化性能,表明在1~9 mmol/L范围内峰电流与抗坏血酸的浓度有较好的线性关系。更多还原

【Abstract】 Glassy carbon electrodes modified with alternating multilayer films containing gadolinium tetrasulfophthalocyanine(GdTs(Pc)2) and diazo-resins(DAR) were fabricated by the electrostatic self-assembly(ESA) technique.The ultraviolet-uisible spectrophotometer(UV-Vis) analysis results indicated that the DAR/GdTs(Pc)2self-assembled multilayer films were successfully fabricated,interface were studied by the Atomic Force Microscope(AFM).The electrocatalytic oxidation of ascorbic acid(AA) on the modified electrode was investigated by cyclic voltammetry technique,and it was found that the modified electrode exhibited good sensitivity for catalytic oxidation of ascorbic acid(AA).It showed the linear relationship between peak current and the concentrations of ascorbic acid(AA) over the range 1 ~9 mmol/L.更多还原
