Metal-catalyzed plastic depolymerization

Cell Reports Physical Science, Год журнала: 2023, Номер 4(5), С. 101341 - 101341

Опубликована: Март 29, 2023

Polymers have become an indispensable part of our daily lives, and today we produce around 370 MT plastic per year. Only about 20% it is being recycled, the rest, 80%, unleashed into environment without appropriate treatment. This calls forth evaluation strategies available for mitigating menace "after-use" waste. Various approaches evolved over a decade are at different levels development. Plastic depolymerization upcycling considered some most prominent long-term solutions. The metal-catalyzed waste to chemical feedstocks has emerged as one promising ways address global pollution. Therefore, this review aims examine methods, notify recent progress, pinpoint current gaps, gauge potential strategy. Both homogeneous heterogeneous catalysts been reported depolymerize various polymers last decade. Considerable advances in metal-mediated polyolefins, polyesters, polycarbonates, polyurethanes, polyamides, polyethers. above produces monomers or intermediates, which can be used again polymerization thus brings back circularity. overview debates usage high temperatures, sophisticated ligands, expensive metals, stoichiometric reagents, etc., depolymerization. Thus, summarizes understanding fundamental science depolymerization, remaining scientific challenges, opportunities.

From Plastic Waste to Treasure: Selective Upcycling through Catalytic Technologies

Advanced Energy Materials, Год журнала: 2023, Номер 13(41)

Опубликована: Сен. 24, 2023

The huge amount of plastic wastes has become a pressing global environmental problem, leading to severe pollution and resource depletion through conventional downcycling technologies like incineration landfilling. In contrast, selective upcycling various plastics offers promising solution for converting waste into valuable products. This review provides comprehensive overview the recent advancements in innovative catalytic technologies, including thermocatalysis, electrocatalysis, photocatalysis. Special emphasis is placed on elucidating reaction mechanisms, activating designated chemical bonds high selectivity, elaborating above techniques terms conditions Finally, application prospects future development trends catalysis are discussed, providing insights realizing sustainable circular economy.
