Abstract The conversion of waste plastic into high‐value‐added chemicals is regarded as a promising approach for relieving global pollution and contributing to the circular economy. Herein, partial calcination strategy developed fabricate zinc oxide/UiO66‐NH 2 (ZnO/UiO66‐NH ) heterojunction, in which ZnO encapsulated porous UiO66‐NH photocatalytic valorization plastic. This preserves framework structure , thus enabling formation with ultra‐small size distributed inside skeleton. synergistic effect obtained ZnO/UiO66‐NH heterojunction facilitates providing an efficient channel carrier/mass transfer guarantees structural stability. As result, exhibits high activity converting polylactic acid (PLA) polyvinyl chloride (PVC) acetic acid, coupled H production. work provides feasible rationally designing photocatalysts, well insight understanding process

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.

The abundant plastic wastes become an imperative global issue, and how to handle these organic gains growing scientific industrial interest. Recently, converting into hydrogen fuel has been investigated, the "waste-to-value" practice accelerates circular economy. To accelerate development of plastic-to-hydrogen conversion, in this review, recent advances conversion via thermochemical, photocatalytic, electrocatalytic routes are analyzed. All thermo-, photo-, electrochemical processes can transform different hydrogen, production efficiency depends heavily on selected techniques, operating parameters, applied catalysts. application rational-designed catalysts promote selective from feedstocks. Further studies process optimization, cost-effective catalyst design, mechanism investigation needed.
