Abstract

Ethylene glycol (EG) is a small-molecule alcohol with a low oxidation potential and is a key monomer in the production of polyethylene terephthalate (PET). The efficient oxidation of EG can further enable the recycling of waste PET. Currently, there are many studies on catalysts for EG oxidation, among which transition metal catalysts (including traditional non-precious metals such as Fe, Co, Ni and other noble metals such as Pt and Pd) have good prospects for application in EG oxidation reactions due to their unique electronic structures. In this study, the synthesis strategy of transition metal catalysts for the electrocatalytic oxidation of EG is summarized and the performance of different types of catalysts in the EG oxidation reaction is reviewed. Advanced characterization methods were used to understand the oxidation mechanism of EG and to control the conversion of EGOR intermediates into target products. Therefore, we need to further explore efficient catalysts for EG oxidation to achieve efficient reactions.

电催化乙二醇氧化过渡金属催化剂的研究进展

乙二醇是一种低氧化电位的小醇分子，也是生产聚对苯二甲酸乙二醇酯（PET）的关键单体。乙二醇高效氧化的实现可以进一步实现废PET的资源化利用。目前，对乙二醇氧化（EGOR）催化剂的研究已经很多，其中过渡金属催化剂（包括Fe、Co、Ni等常规非贵金属和Pt、Pb等贵金属）由于其独特的电子结构，在乙二醇氧化反应中具有很好的应用前景。本文综述了用于EG电催化氧化的过渡金属催化剂的合成策略，并对不同类型催化剂在乙二醇氧化中的性能进行了综述。利用先进的表征方法了解EGOR的氧化机理，并控制EGOR中间体转化为目标产物。因此，我们需要进一步探索高效的乙二醇氧化催化剂，以实现高效反应。
