本文报道了羧酸功能化单壁碳纳米管（SWCNT）在2，3-四-（4-氧代苯甲酰胺）酞菁钴（II）-单壁碳纳米管复合物（CoTOBPC-SWCNT）的合成、表征及其在电催化氧化灭草胺中的应用。用循环伏安法、计时电流法和电化学阻抗谱法在修饰玻碳电极上检测了杀虫脒。催化速率常数为1.6× 103 M − 1 s − 1，表观电子转移速率常数为1.5×10−5cms−1。线性动态范围为1.0×10−6-3.0×10− 5 M，灵敏度为1.13Amol− 1 Lcm −2。
In this paper we report on the use of carboxylic acid functionalized single walled carbon nanotubes (SWCNT) in the synthesis of 2,(3)-tetra-(4-oxo-benzamide)phthalocyaninato cobalt (II)–single walled carbon nanotube conjugates (CoTOBPc–SWCNT), their characterization and application in the electrocatalytic oxidation of amitrole. Cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy were used for the detection of amitrole on the modified glassy carbon electrode. The catalytic rate constant was 1.6×103M−1s−1and the apparent electron rate transfer constant was 1.5×10−5cms−1. The linear dynamic range was 1.0×10−6–3.0×10−5M, with a sensitivity of ∼1.13Amol−1Lcm−2.
