Abstract
Ethylene glycol (EG) is a biomass derivative of polyethylene terephthalate (PET), and its electrocatalytic conversion into high-value chemicals has sparked widespread interest. This study reviews the most recent research development in electrocatalysis-based EG to glycolic acid (GA) conversion. Firstly, the strategies and research results of modulating the electronic structure of catalysts for efficient selective GA production from EG are reviewed. Second, by reviewing the data of in-situ Fourier transform infrared spectroscopy and in-situ electrochemically attenuated total reflection surface enhanced infrared absorption spectroscopy, the reaction pathway and catalytic mechanism of EG partial oxidation to GA were clarified. Finally, the design and regulation of catalysts for selective oxidation of EG by electrocatalysis in the future are prospected.
