Rapid industrialization and development have led to a tremendous increase in the use of various types plastic commodities daily life. For past several years, pollution has become global issue, posing serious threat mankind. The primary issue with increasing is lack proper management which created huge havoc environment. From initial phase waste management, been discarded, recycled, downcycled, or dumped into landfills large proportion, causing extreme damage ecosystem. Conventionally, treated via thermal processes such as pyrolysis incineration plants require amount capital and, therefore, harms aim circular economy. Chemical upcycling gaining attention high-potential catalytic strategy convert plastics, polyethylene terephthalate, polyethylene, polystyrene, etc. fuels, functionalized polymers, other value-added chemicals having direct impact on affordability viability. In this review, we focused photocatalysis, electrocatalysis, photoelectrocatalysis effective efficient technologies.

Abstract Only a small proportion of global plastic waste is recycled, which most mechanically recycled into lower quality materials. The alternative, chemical recycling, enables renewed production pristine materials, but generally comes at high energy cost, particularly for processes like pyrolysis. This review focuses on light-driven approaches chemically recycling and upcycling waste, with emphasis reduced consumption selective transformations not achievable heat-driven methods. We focus challenging to recycle backbone structures composed mainly C‒C bonds, lack functional groups i.e., esters or amides, that facilitate e.g., by solvolysis. discuss the use light, either in conjunction heat drive depolymerization monomers via photocatalysis transform polymers valuable molecules. structural prerequisites these are outlined, highlighting their advantages as well limitations. conclude an outlook, addressing key challenges, opportunities, provide guidelines future photocatalyst (PC) development.

Plastics are ubiquitous and indispensable in our daily life because of their low cost, portability, durability, processability. However, due to the overuse, short service life, chemical inert character, accumulated discarded plastics pose a great threat sustainable development ecology environment. Photocatalysis represents highly promising technology transforming plastic wastes into value‐added products via green mild method. In this perspective, advantages photocatalysis discussed compared with other catalysis technologies including thermal catalysis, electrocatalysis, enzyme catalysis. Then possible photocatalytic upcycling path is clarified under different experimental conditions. The types that can be upcycled by photocatalysis, integrating modus between photocatalysts as well modulation product selectivity also emphasized. Finally, challenges insights future waste fields presented. It expected timely critical review provides instructive guidance for design high efficiency toward upcycling.
