The recycling of plastic waste is likely one of the most pressing points within the 21st century owing to its detrimental impression on the setting and human well being. Nevertheless, it’s enormously difficult to develop extra environment friendly, low-cost and basic strategies able to selectively changing plastic waste into added-value and separable chemical substances whereas limiting their distribution. Right here, we report a basic electrocatalytic technique for the selective upcycling of varied polyester plastics into added-value chemical substances by a CuCo2O4/Ni foam catalyst below delicate circumstances. Specifically, polyethylene terephthalate (PET) was upcycled into terephthalate and formate with excessive effectivity and selectivity (>86%) even at a excessive present density of 100 mA cm−2. The electrocatalytic response mechanism was totally elucidated by electrochemical in situ FTIR, NMR and DFT calculations. This work not solely develops a superior electrocatalyst for upcycling varied polyester plastics, but in addition supplies steering for the design of latest and environment friendly electrocatalysts.
