Abstract

From the environmental perspective, it is essential to develop eco-friendly materials for water and wastewater treatment that can be integrated into the most effective technologies till now employed in this field. In this regard, biobased hydrogels (BBHs) represent a simple and free from harmful by-products solution to mitigate global water pollution. BBHs are natural polymers very interesting for their availability, price competitiveness, excellent biodegradability, biocompatibility, hydrophilicity, and superior physicochemical performance in water treatment. This review outlines the recent progress in developing and applying BBHs hydrogels in electrochemical water treatments, from advanced oxidation processes to microbial fuel cells, capacitive deionization, and the most innovative technologies based on the cogeneration of clean water and electricity. In addition, this review covers the BBH’s current limitations, such as low mechanical performance and poor stability, and provides valuable insights into the efficient applications of BBHs in the electrochemical treatments of water purification.

生物基水凝胶在电化学水处理中的应用

从环境的角度来看，开发用于水和废水处理的环保材料至关重要，这些材料可以集成到该领域目前使用的最有效的技术中。在这方面，生物基水凝胶（BBHs）代表了一种简单且无有害副产品的解决方案，可以减轻全球水污染。BBHs是一种天然聚合物，因其可获得性、价格竞争力、良好的生物降解性、生物相容性、亲水性以及在水处理中优越的物理化学性能而备受关注。本文综述了近年来BBHs水凝胶在电化学水处理中的开发和应用进展，从高级氧化工艺到微生物燃料电池，电容去离子，以及基于清洁水和电热电联产的最具创新性的技术。此外，本文综述了目前BBH的局限性，如机械性能低和稳定性差，并为BBH在水净化电化学处理中的有效应用提供了有价值的见解。

期刊介绍： The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
