Electrocatalytic dehalogenation in the applications of organic synthesis and environmental degradation

Abstract Electrocatalytic dehalogenation technology is a promising approach for the synthesis of chemicals (such as pesticides and pharmaceutical intermediates) and the disposal of halogenated organic pollutants. Compared with the traditional chemical reduction technology, the electrocatalytic reduction dehalogenation method has the advantages of high efficiency, controllable operation, and reduced secondary pollution. This review systematically consolidates the recent advances in the electrocatalytic dehalogenation in the application of organic synthesis and environmental degradation, focusing on the involved mechanisms, and influences factors (e.g., electrocatalysts, solution environment, and reaction conditions) on the performance of electrocatalytic dehalogenation. Furthermore, the latest characterization and analytical methods and the industrial application of electrocatalytic dehalogenation technology are summarized. Lastly, the existing challenges and perspectives are proposed for efficient electrocatalytic dehalogenation.
