Oxidative degradation is a powerful method to degrade plastics into oligomers and small oxidized products. While thermal energy has been conventionally employed as an external stimulus, recent advances in photochemistry have enabled photocatalytic oxidative of polymers under mild conditions. This tutorial review presents overview degradation, from its earliest examples emerging strategies. briefly discusses the motivation development with focus on underlying mechanisms. Then, we will examine modern studies primarily relevant catalytic degradation. Lastly, highlight some unique using unconventional approaches for polymer such electrochemistry.

The chemical recycling of poly(ethylene terephthalate) (PET) plastic by catalytic glycolysis is an enabling technology for the circular economy that attracting burgeoning academic and commercial interest. Ionic liquids are emerging as a versatile catalyst class this transformation, yet general strategies how both high activity biodegradability can be incorporated into design have not emerged. Beginning with active literature incorporating phosphonium cation concern from standpoint, structure relationship study involving 33 systematically varied ionic liquid catalysts was undertaken, which highlighted (inter alia) contribution lipophilicity to identified hydrocinnamate benzoate counteranions highly serviceable. This allowed superior, high-activity catalyst, remained biodegradative concern. Subsequently, structure–activity relationships principles uncovered in informed biodegradability/activity-guided approach design, leading development three were either known readily biodegradable or comprised anions cations. All significantly outperformed benchmark cholinium ion-based at low loadings 1 mol %.

Abstract Chlorinated polymers have made enormous contributions to materials science and are commercially produced on a large scale. These chlorinated could be recycled as chlorine sources efficiently produce valuable compounds owing their facile release of HCl. Although the thermal stability PVDC is low compared PVC, this can advantageous in terms easy fast dehydrochlorination. Herein, we report an efficient electrochemical chlorination using poly(vinylidene chloride) (PVDC) source that works undivided cell applies good number examples. This method commodity such waste PVDC‐PVC pharma blister film, PVDC‐PO multilayer food packaging, compression molded sheets Ixan (with heat stabilizer) with similar efficiency. Furthermore, also provides dechlorination up 98 %, leading unsaturated dechlorinated material. Converting into more stable compounds, harmful chlorine‐containing gases during incineration minimized. Additionally, not only restricted batch processes but electroflow process for electrosynthesis has been demonstrated.
