Herein, we explore the holistic integration of magnetite-based photocatalysts and techno-economic analysis (TEA) as a sustainable approach in wastewater treatment aligned with the Sustainable Development Goals (SDGs). While considerable attention has been devoted to photocatalytic dye degradation, the nexus between these processes and techno-economic considerations remains relatively unexplored. The review comprehensively examines the fundamental characteristics of magnetite-based photocatalysts, encompassing synthesis methods, composition, and unique properties. It investigates their efficacy in photocatalytic degradation, addressing homogeneous and heterogeneous aspects while discussing strategies to optimize photodegradation efficiency, including curbing electron-hole recombination and mitigating scavenging effects and interference by ions and humic acid. Moreover, the management aspects of magnetite-based photocatalysts are examined, focusing on their reusability and regeneration post-dye removal, along with the potential for reusing treated wastewater in relevant industrial applications. From a techno-economic perspective, the study evaluates the financial feasibility of deploying magnetite-based photocatalysts in wastewater treatment, correlating reduced pollution and the marketing of treated water with social, economic, and environmental objectives. By advocating the integration of magnetite-based photocatalysts and TEA, this paper contributes insights into scalable and profitable sustainable wastewater treatment practices. It underscores the alignment of these practices with SDGs, emphasizing a comprehensive and holistic approach to managing wastewater in ways that meet environmental, economic, and societal objectives.
在此，我们探讨基于磁铁矿的光催化剂与技术经济分析（TEA）的整体整合，将其作为一种与可持续发展目标（SDGs）相一致的可持续废水处理方法。虽然光催化染料降解已受到相当多的关注，但这些过程与技术经济考量之间的联系仍相对未被探索。本综述全面研究了基于磁铁矿的光催化剂的基本特性，包括合成方法、组成和独特性能。研究了它们在光催化降解中的功效，探讨了均相和非均相方面，同时讨论了优化光降解效率的策略，包括抑制电子 - 空穴复合以及减轻离子和腐殖酸的清除效应和干扰。此外，还研究了基于磁铁矿的光催化剂的管理方面，重点关注其在染料去除后的可重复使用性和再生，以及在相关工业应用中回用处理后废水的潜力。从技术经济角度来看，该研究评估了在废水处理中部署基于磁铁矿的光催化剂的财务可行性，将减少污染和处理后水的销售与社会、经济和环境目标相关联。通过倡导基于磁铁矿的光催化剂与TEA的整合，本文为可扩展且有利可图的可持续废水处理实践提供了见解。它强调了这些实践与可持续发展目标的一致性，强调以满足环境、经济和社会目标的方式对废水进行全面和整体管理的方法。
