Abstract

Converting plastic wastes into valuable chemicals and fuels provides an attractive alternative solution. However, current catalytic technologies often require rigorous conditions such as high temperature, high pressure, and caustic bases, resulting in high energy costs and secondary environmental contamination. Recently, integrating plastic upgrading with photocatalysis into one reaction system has been proven to be an effective approach that can sufficiently utilize photogenerated electrons and holes to achieve sustainable economic development. In this review, we summarize current advances in coupling plastic upgrading and photocatalysis by focusing on the catalyst selection, design principles of these integrated systems, including photoreforming H₂ evolution, photocoupling CO₂ reduction, and photo-oxidation, and the underlying catalytic mechanisms, including holes and reactive oxygen species mechanisms. We also assess the economic feasibility and environmental impact of these integrated technologies based on techno-economic analysis and life cycle assessment. The ongoing challenges and future research directions in this field are critically discussed. We believe that this review will inspire more creativity in designing such win–win coupled photoredox reaction systems.

耦合塑料升级和光催化：催化机理和设计原则

将塑料废物转化为有价值的化学品和燃料提供了一个有吸引力的替代解决方案。然而，目前的催化技术往往需要苛刻的条件，如高温、高压和苛性碱，导致高能源成本和二次环境污染。近年来，将塑料升级和光催化结合为一个反应体系已被证明是充分利用光电子和空穴实现经济可持续发展的有效途径。本文综述了塑料升级和光催化耦合的研究进展，重点介绍了催化剂的选择、光重整析氢、光耦合CO2还原和光氧化等集成系统的设计原则，以及潜在的催化机制，包括孔和活性氧机制。我们还基于技术经济分析和生命周期评估评估了这些综合技术的经济可行性和环境影响。对该领域面临的挑战和未来的研究方向进行了批判性的讨论。我们相信这一综述将在设计这种双赢耦合光氧化还原反应体系方面激发更多的创造力。
