还原加氢脱氯是提高甲草胺等氯化除草剂降解率的有效方法，甲草胺是地下水和地表水中常见的除草剂。在本研究中，合成了一个具有8个三氮唑单元和烷基链的钴卟啉配合物CoPor8T，用于催化甲草胺的还原加氢脱氯反应。结合伏安法、光谱学和电光谱学技术进行机理研究。电催化后，在 为1.8Vvs.Fc/Fc+、氯离子浓度为96 %时，转化率为84 %。本工作为电催化氯化除草剂修复提供了一条分子催化剂的新途径。
Reductive hydrodechlorination is an effective approach to enhance the degradation rate of chlorinated herbicides such as alachlor, which are frequently detected in ground and surface water. In this study, a cobalt porphyrin complex with eight triazole units and alkyl chains,CoPor8T, was synthesized to catalyze the reductive hydrodechlorination of alachlor. Mechanistic study was performed using a combination of voltametric, spectroscopic, and electrospectroscopic techniques. A conversion yield of 84 % at −1.8 V vs. Fc/Fc+and chloride ion concentration of 96 % was obtained after electrocatalysis. This work provides a new avenue of using molecular catalysts for electrocatalytic chlorinated herbicide remediation.
