The persistent presence of Pharmaceuticals and Personal Care Products (PPCPs) in aquatic environments poses a significant risk to both human health and ecosystems, with conventional water treatment methods often unable to effectively remove these contaminants. Recent research has identified bimetallic nanoparticles as a promising and eco-friendly solution for PPCP remediation, owing to their enhanced catalytic properties and the synergistic effects between the metals. This review critically examines the synthesis, characterization, and application of bimetallic nanoparticles for the degradation of PPCPs in water. Key synthetic approaches, particularly green synthesis methods, are explored, emphasizing their ability to control nanoparticle morphology, size, and composition. We highlight the novel catalytic mechanisms employed by bimetallic nanoparticles, including electron transfer, surface reactions, and adsorption processes, which contribute to efficient PPCP removal. Furthermore, the influence of critical factors such as nanoparticle size, composition, and surface functionalization on catalytic efficiency is analyzed. Key findings include the superior performance of bimetallic nanoparticles over monometallic counterparts, with specific emphasis on their ability to degrade a wide range of PPCPs under mild conditions. However, challenges such as scalability, stability, and environmental impact remain. This review also provides insights into the future directions for bimetallic nanoparticle development, stressing the importance of interdisciplinary research and collaborative efforts to optimize their design for large-scale, sustainable water treatment applications. Overall, this work offers a comprehensive understanding of how bimetallic nanoparticles can be optimized for sustainable water treatment solutions, highlighting their potential to mitigate the adverse effects of PPCPs on both ecosystems and public health.
药品和个人护理产品（PPCPs）在水生环境中的持续存在对人类健康和生态系统都构成了重大风险，传统的水处理方法往往无法有效去除这些污染物。最近的研究已将双金属纳米颗粒确定为一种有前景的、生态友好的PPCP修复解决方案，这得益于其增强的催化性能以及金属之间的协同效应。本文综述批判性地研究了双金属纳米颗粒在水中降解PPCPs的合成、表征及应用。探索了关键的合成方法，尤其是绿色合成方法，强调了它们控制纳米颗粒形态、尺寸和组成的能力。我们突出了双金属纳米颗粒所采用的新型催化机制，包括电子转移、表面反应和吸附过程，这些机制有助于高效去除PPCPs。此外，还分析了纳米颗粒尺寸、组成和表面功能化等关键因素对催化效率的影响。主要发现包括双金属纳米颗粒相对于单金属纳米颗粒具有更优异的性能，特别强调了它们在温和条件下降解多种PPCPs的能力。然而，诸如可扩展性、稳定性和环境影响等挑战仍然存在。本文综述还提供了双金属纳米颗粒未来发展方向的见解，强调了跨学科研究和合作努力对于优化其设计以用于大规模可持续水处理应用的重要性。总体而言，这项工作全面阐述了如何优化双金属纳米颗粒以实现可持续水处理解决方案，突出了它们减轻PPCPs对生态系统和公众健康不利影响的潜力。
