Plastic waste, particularly microplastics, is a concerning environmental problem caused by the rapidly increasing production and use of plastic products as well as their improper handling. Therefore, this review presents a comprehensive critical discussion on plastic waste conversion into value-added fuels, specifically hydrogen (H). This review particularly focuses on the catalytic materials employed in the catalyst-assisted pyrolysis of waste plastic into H. Moreover, the advances in catalytic pyrolysis reactors are extensively discussed. Furthermore, this review considers the circular economy aspect of the pyrolysis of plastic waste in terms of the generated liquid, solid, and gas products. Lastly, the review summarizes the topic with a conclusion and future perspectives. This review offers insights into the prevailing status of plastic waste management under the circular economy framework in light of the increasing plastic waste pollution, supporting long-term sustainability.
塑料垃圾，尤其是微塑料，是一个令人担忧的环境问题，这是由塑料制品的产量和使用迅速增加以及处理不当造成的。因此，本综述对塑料垃圾转化为增值燃料，特别是氢气（H）进行了全面的批判性讨论。本综述特别关注用于将废塑料催化热解为氢气的催化材料。此外，还广泛讨论了催化热解反应器的进展。此外，本综述从产生的液体、固体和气体产物的角度考虑了塑料垃圾热解的循环经济方面。最后，本综述以结论和未来展望总结了该主题。鉴于塑料垃圾污染日益严重，本综述提供了在循环经济框架下塑料垃圾管理现状的见解，支持长期可持续性发展。
