Abstract

This study presents a novel photocatalytic composite, AgPO/GCN/FeNi-BTC/CQD (AGF-CQD), synthesized via a green microwave-assisted hydrothermal method, integrating carbon quantum dots (CQDs) derived from aquaculture by-products. The AGF-CQD composite demonstrates superior photocatalytic activity, attributed to enhanced visible light absorption, efficient charge transfer, and improved electron-hole separation. Analytical techniques such as photoluminescence (PL), UV–Vis diffuse reflectance spectroscopy (DRS), and transmission electron microscopy (TEM) validate the composite’s structural and optical properties. In tetracycline degradation tests, AGF-CQD outperforms AgPO, GCN, FeNi-BTC, and 20 % AGF samples by 5.5, 3.6, 4.4, and 2.3 times, respectively, achieving a remarkable 98.4 % removal rate after 60 min under visible light. Factors affecting degradation, including dosage, concentration, pH, and water source, are investigated. Furthermore, an operating mechanism based on electrochemical properties and the involvement of radicals is proposed. This research offers a sustainable approach to synthesizing efficient photocatalysts for environmental remediation.

增强可见光下的四环素光催化降解：释放 Z 型 Ag3PO4/GCN/FeNi-BTC 光催化剂与碳量子点的协同作用

本研究采用绿色微波辅助水热法合成了一种新型光催化复合材料--AgPO/GCN/FeNi-BTC/CQD（AGF-CQD），其中集成了从水产养殖副产品中提取的碳量子点（CQD）。AGF-CQD 复合材料具有优异的光催化活性，这归功于其增强的可见光吸收能力、高效的电荷转移能力和更好的电子-空穴分离能力。光致发光（PL）、紫外可见漫反射光谱（DRS）和透射电子显微镜（TEM）等分析技术验证了该复合材料的结构和光学特性。在四环素降解测试中，AGF-CQD 的性能分别是 AgPO、GCN、FeNi-BTC 和 20% AGF 样品的 5.5 倍、3.6 倍、4.4 倍和 2.3 倍，在可见光下 60 分钟后的去除率高达 98.4%。研究了影响降解的因素，包括用量、浓度、pH 值和水源。此外，还提出了基于电化学特性和自由基参与的运行机制。这项研究为合成用于环境修复的高效光催化剂提供了一种可持续的方法。
