Abstract

As an important water and seawater degradable plastic monomer, glycolic acid can be synthesized by selective oxidation of ethylene glycol. This review recapitulates recent advances in electrocatalytic ethylene glycol oxidation reaction (EGOR) from the aspects of catalytic performance and reaction mechanism. For catalytic performance evaluation, target product yield and space-time yield are correlated and analyzed for electrocatalytic and thermocatalytic EGOR systems. To elucidate the rationale behind the electrocatalytic selective oxidation of ethylene glycol, previous works using in situ Fourier transform infrared spectroscopy, online differential electrochemical mass spectrometry, ion chromatography, and theoretical calculations to investigate EGOR are systematically reviewed. Finally, the advantages of electrocatalytic EGOR are summarized by comparing electrocatalytic and thermocatalytic processes.

乙二醇电催化选择性氧化:催化剂的发展和反应机理的简要综述，并与热催化氧化过程进行了比较

乙醇酸是一种重要的水和海水可降解塑料单体，乙二醇选择性氧化可合成乙醇酸。本文从催化性能和反应机理两方面综述了电催化乙二醇氧化反应(EGOR)的研究进展。为了评价催化性能，对电催化和热催化EGOR系统的目标产物收率和空时收率进行了关联分析。为了阐明乙二醇电催化选择性氧化背后的原理，本文系统地回顾了以前使用原位傅里叶变换红外光谱、在线差分电化学质谱、离子色谱和理论计算来研究EGOR的工作。最后，通过对电催化和热催化工艺的比较，总结了电催化EGOR的优点。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
