Abstract

The use of waste biomass as a precursor for carbon electrodes in electrochemical water treatment not only offers a resourceful solution to waste management challenges but also constitutes a substantial contribution to the circular economy. This study critically reviews recent advancements in utilizing waste biomass derived carbon materials for electrochemical water treatment, focusing on applications like electrochemical advanced oxidation processes (e-AOPs) and capacitive deionization. The versatility of carbon materials, with characteristics such as extensive specific surface areas, high electrical conductivity, and tunable hydrophobicity, positions them as pivotal for various electrochemical applications. This short review extends to bioelectrochemical systems (BES), highlighting the potential of waste-derived carbon materials to enhance BES electrode efficiency while significantly reducing manufacturing costs. The comprehensive assessment of recent developments provides insights into strengths and weaknesses in the use of these materials and future research directions for optimizing electro/bioelectrochemical water treatment processes on a broader scale.

推进循环经济：对用于（生物）电化学水处理的废弃生物质衍生碳电极的重要见解

在电化学水处理中使用废弃生物质作为碳电极的前体，不仅为解决废物管理难题提供了资源解决方案，还为循环经济做出了巨大贡献。本研究对利用废弃生物质衍生碳材料进行电化学水处理的最新进展进行了评述，重点关注电化学高级氧化工艺（e-AOPs）和电容去离子等应用。碳材料具有多功能性，例如比表面积大、导电性高和疏水性可调等特点，因此在各种电化学应用中具有举足轻重的地位。这篇简短的综述扩展到了生物电化学系统（BES），强调了从废弃物中提取的碳材料在提高 BES 电极效率的同时显著降低制造成本的潜力。通过对最新发展的全面评估，我们可以深入了解这些材料在使用过程中的优缺点，以及在更大范围内优化电/生物电化学水处理工艺的未来研究方向。
