The global production and recycling of plastics are seriously imbalanced, and how to deal with and dispose of large amounts of waste plastics has become a focus of global concern. The upgrading of high-value resource recovery technology has made the recycling of waste plastics a reality. Waste plastic-derived functional carbon materials and catalysts have been used in separation, catalysis, fluorescence sensing, and energy storage, etc. Although some progress has been made in the chemical recycling of waste plastics at present, there is still a significant knowledge gap in the application of derived high-value products. This paper reviews the applications of waste plastic-derived functional materials in adsorption, separation, degradation, and energy storage. The application prospects of waste plastic-derived functional materials are analyzed in detail from multiple aspects. The advantages of waste plastic-derived materials in wastewater treatment, the challenges and existing knowledge gaps in the preparation and application processes are discussed. At present, most of the research is still at the theoretical stage. How to achieve the replication and transfer of the preparation process and application scenarios from small-scale to large-scale is a key issue worth considering. In general, the chemical conversion of waste plastics and the output of high-value functional materials is a wise choice, which can further reduce waste plastics in the environment, but the key factors still need to be explored. This paper provides a theoretical basis for the preparation and application of waste plastic-derived functional materials and offers new insights for promoting the development of this field.
全球塑料的生产和回收严重失衡，如何处理和处置大量废弃塑料已成为全球关注的焦点。高价值资源回收技术的升级使废弃塑料的回收成为现实。废塑料衍生的功能碳材料和催化剂已应用于分离、催化、荧光传感和储能等领域。尽管目前废塑料的化学回收已取得一些进展，但在衍生高价值产品的应用方面仍存在显著的知识空白。本文综述了废塑料衍生功能材料在吸附、分离、降解和储能方面的应用。从多个方面详细分析了废塑料衍生功能材料的应用前景。讨论了废塑料衍生材料在废水处理中的优势、制备和应用过程中的挑战以及现有的知识空白。目前，大多数研究仍处于理论阶段。如何实现制备过程和应用场景从小规模到大规模的复制和转移是一个值得考虑的关键问题。总体而言，废塑料的化学转化和高价值功能材料的产出是一个明智的选择，这可以进一步减少环境中的废塑料，但关键因素仍有待探索。本文为废塑料衍生功能材料的制备和应用提供了理论依据，并为推动该领域的发展提供了新的见解。
