The exponential growth of the global population in the digital era has accelerated urbanization and industrialization, leading to severe complex water pollution from the discharge of toxic dyes into aquatic ecosystems. Two dimensional (2D) MXene-based nano-adsorbents recently emerged as promising candidates for developing sustainable wastewater remediation technologies due to their tunable physicochemical properties, including a high negative zeta potential, a large specific surface area, exceptional adsorption capacity, superior electrical and thermal conductivity, hydrophilicity, and rich surface chemistry. Strategic optimization approaches for MXenes, encompassing interlayer spacing modification, surface engineering, stoichiometric tuning, morphological control, bandgap engineering, membrane fabrication, hybridization, and functionalization, have significantly enhanced their adsorptive performance and dye removal efficiency for real-time wastewater treatment applications. This comprehensive review examines the latest advances in MXene-based nano-adsorbent engineering and their implementation as key components in wastewater treatment strategies for efficient dye removal from industrial effluents, providing fundamental insights into dye-MXene interactions to elucidate underlying complex removal mechanisms. The review highlights the sustainable characteristics of MXene-based nano-adsorbents, including their dye removal capacity, regeneration potential, recyclability, catalytic efficiency, and enhanced physicochemical properties, while addressing critical challenges, such as toxicity concerns, biocompatibility issues, and scalability limitations, that currently hinder their translation from the laboratory to the market. Innovative solutions are proposed through the integration of digital-age technologies, particularly artificial intelligence and machine learning approaches, with the implementation of these recommendations facilitating the establishment of MXene-based nano-adsorbents as sustainable alternatives to conventional commercial adsorbents. This aligns with the UN's Sustainable Development Goals and contributes to the principles of One Health, promoting global welfare.
数字时代全球人口的指数增长加速了城市化和工业化进程，导致有毒染料排放到水生生态系统中，造成了严重而复杂的水污染。基于二维（2D）MXene的纳米吸附剂最近成为开发可持续废水修复技术的有前景的候选材料，因为它们具有可调节的物理化学性质，包括高负zeta电位、大比表面积、出色的吸附能力、优异的电导率和热导率、亲水性以及丰富的表面化学性质。针对MXene的策略优化方法，包括层间距修饰、表面工程、化学计量调整、形态控制、带隙工程、膜制备、杂化和功能化，显著提高了它们的吸附性能以及对实时废水处理应用的染料去除效率。这篇综述全面考察了基于MXene的纳米吸附剂工程的最新进展，以及它们作为废水处理策略的关键组成部分用于从工业废水中高效去除染料的应用情况，提供了关于染料与MXene相互作用的基本见解，以阐明潜在的复杂去除机制。该综述强调了基于MXene的纳米吸附剂的可持续特性，包括它们的染料去除能力、再生潜力、可回收性、催化效率以及增强的物理化学性质，同时解决了目前阻碍它们从实验室转化到市场的关键挑战，如毒性问题、生物相容性问题和可扩展性限制。通过整合数字时代技术，特别是人工智能和机器学习方法，提出了创新解决方案，实施这些建议有助于将基于MXene的纳米吸附剂确立为传统商业吸附剂的可持续替代品。这与联合国的可持续发展目标相一致，并有助于促进全球福祉的“同一健康”原则。
