摘要
With large quantities and natural resistance to degradation,plastic waste raises growing environmental concerns in the world.To achieve the upcycling of plastic waste into value-added products,the electrocatalytic-driven process is emerging as an attractive option due to the mild opera-tionconditions,highreactionselectivity,andlowcarbonemission.Herein,this review provides a comprehensive overview of the upgrading of plastic waste via electrocatalysis.Specifically,key electrooxidation processes including the target products,intermediates and reaction pathways in the plastic electro-reforming process are discussed.Subsequently,advanced electrochemical systems,including the integration of anodic plastic monomer oxidation and value-added cathodic reduction and photo-involved electrolysis processes,are summarized.The design strategies of electrocatalysts with enhanced activity are highlighted and catalytic mechanisms in the electrocatalytic oxidation of plastic waste are eluci-dated.To promote the electrochemistry-driven sustainable upcycling of plastic waste,challenges and opportunities are further put forward.
