Excessive production of waste polyethylene terephthalate (PET) poses an ecological challenge, which necessitates developing technologies to extract the values from end-of-life PET. Upcycling has proven effective in addressing low profitability current recycling strategies, yet existing upcycling operate under energy-intensive conditions. Here we report a cascade strategy steer transformation PET into glycolate overall yield 92.6% ambient The approach involves setting up robust hydrolase with 95.6% depolymerization ethylene glycol (EG) monomer within 12 h, followed by electrochemical process initiated CO-tolerant Pd/Ni(OH)

Abstract Electrochemical upcycling of end‐of‐life polyethylene terephthalate (PET) using renewable electricity offers a route to generate valuable chemicals while processing plastic wastes. However, it remains huge challenge design an electrocatalyst with reliable structure‐property relationships for PET valorization. Herein, spinel Co 3 O 4 rich oxygen vacancies improved activity toward formic acid (FA) production from hydrolysate is reported. Experimental investigations combined theoretical calculations reveal that incorporation V into not only promotes the generation reactive hydroxyl species (OH * ) at adjacent tetrahedral 2+ (Co2+ Td), but also induces electronic structure transition octahedral 3+ (Co3+ Oh) Oh), which typically functions as highly‐active catalytic sites ethylene glycol (EG) chemisorption. Moreover, enlarged Co‐O covalency induced by facilitates electron transfer EG OH via Co2+ Oh‐O‐Co2+ Td interaction and following C─C bond cleavage direct oxidation glyoxal intermediate pathway. As result, ‐Co catalyst exhibits high half‐cell oxidation, Faradaic efficiency (91%) productivity (1.02 mmol cm −2 h −1 FA. Lastly, demonstrated hundred gram‐scale formate crystals can be produced real‐world bottles two‐electrode electroreforming, yield 82%.
