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.

Advancing BiVO4 Photoanode Activity for Ethylene Glycol Oxidation via Strategic pH Control

“…Polyethylene terephthalate (PET), a widely used plastic, is a prime candidate for degradation and recycling due to its versatile properties [ 21 , 22 ]. Ethylene glycol, a hydrolysis byproduct of PET, is particularly notable for its annual production volume and favorable properties, including low toxicity and high energy density [ 23 , 24 , 25 , 26 ]. The selective oxidation of biomasses such as ethylene glycol could lead to the production of valuable compounds like glycolic acid, formic acid, and oxalic acid [ 25 , 27 ].…”
