High entropy photocatalysts for energy and environmental applications

Chemical Synthesis, Journal Year: 2025, Volume and Issue: 5(2)

Published: March 18, 2025

Today, the energy and environmental crisis originating from use of fossil fuels carbon dioxide (CO2) emissions has become a common concern in lives people. Photocatalysis is promising clean technology receiving much attention. There are diverse strategies to enhance efficiency photocatalysis, high entropy photocatalysts (HEPs) show great potential as new efficient photocatalysts. The tunability HEPs provides more possibilities for design electronic structure catalysts, which leads separation electron-hole pairs substantially enhances photocatalytic performance. This review discusses composition HEPs, their advantages characterization, prediction, latest applications various systems. Finally, we discuss summarize challenges prospects HEPs.

Reductive Upcycling of Polyolefins, Polyesters and Mixed Plastic Wastes to Valuable Chemicals: Bridging Chemical Catalysis With Plastic Waste Management

Advanced Sustainable Systems, Journal Year: 2025, Volume and Issue: unknown

Published: March 20, 2025

Abstract The unmatched applications of plastic commodities are evident from the enormous production, reaching over 400 million tons per year in recent times. Contrastingly, lack proper management leads to a large accumulation waste, majorly including polyolefins and polyesters. Conventional methods possess significant drawbacks like cost‐ineffectiveness greenhouse gas emissions. Over last decade, chemical processes have shown promising potential for but only hold 0.1% share recycling. catalytic offer excellent protocols obtain high‐value liquid fuels, waxes, chemicals waste. This review presents an elaborate discussion on state art reductive upcycling polyolefins, polyesters, mixed initially discusses alarming statistics plastics conventional approaches followed by introduction processes. Further, various recently reported strategies been elaborated detail catalyst deactivation, technoeconomic analysis, life cycle assessment deeper understanding current this research field. Finally, detailed summary along with existing challenges countermeasures is discussed open new avenues waste research.

Review Upcycling of Waste Plastics into Value-Added Chemicals Jin Xu and Jing Zhang * State Key Laboratory Chemical Engineering, East China University Science Technology, 130 Meilong Road, Shanghai 200237, Correspondence: [email protected] Received: 8 November 2024; Revised: 22 January 2025; Accepted: 24 March Published: 27 2025 Abstract: The rapid increase in plastic production has led to a severe waste crisis, driving the development various recycling technologies mitigate this growing issue. However, these often encounter substantial economic environmental challenges their implementation. An increasingly attractive alternative is chemical upcycling, which can transform plastics value-added chemicals. This review systematically examines upcycling applicable major commercial plastics, including polyethylene terephthalate (PET), polyolefins, polystyrene (PS), polyvinyl chloride (PVC). We focus on key strategies such as solvolysis, catalytic pyrolysis, hydrocracking hydrogenolysis, along with some emerging approaches electrocatalysis photooxidation, aiming summarize trends plastics.
