Carbon-based functional materials hold the key for solving global challenges in the areas of water scarcity and the energy crisis. Although carbon nanotubes (CNTs) and graphene have shown promising results in various fields of application, their high preparation cost and low production yield still dramatically hinder their wide practical applications. Therefore, there is an urgent call for preparing carbon-based functional materials from low-cost, abundant, and sustainable sources. Recent innovative strategies have been developed to convert various waste materials into valuable carbon-based functional materials. These waste-derived carbon-based functional materials have shown great potential in many applications, especially as sorbents for water remediation and electrodes for energy storage. Here, the research progress in the preparation of waste-derived carbon-based functional materials is summarized, along with their applications in water remediation and energy storage; challenges and future research directions in this emerging research field are also discussed.
基于碳的功能材料是解决水资源短缺和能源危机等全球性挑战的关键。尽管碳纳米管（CNTs）和石墨烯在各个应用领域都表现出了很有前景的结果，但它们高昂的制备成本和低的生产产量仍然严重阻碍了它们的广泛实际应用。因此，迫切需要从低成本、丰富和可持续的来源中制备碳基功能材料。最近已经开发出了创新性策略，可将各种废料转化为有价值的碳基功能材料。这些源自废料的碳基功能材料在许多应用中表现出巨大的潜力，特别是作为水修复的吸附剂和储能的电极。在这里，总结了制备源自废料的碳基功能材料的研究进展，以及它们在水修复和储能方面的应用；还讨论了这个新兴研究领域的挑战和未来研究方向。
