Abstract

In this paper, Ti₃C₂ QDs and Fe-ZIF-8 were synthesized by a straightforward hydrothermal method. Fe-ZIF-8 was pyrolyzed at high temperatures to obtain Fe-nanoclusters (Fe-NC). Then Fe-NC is mixed with Ti₃C₂ QDs to form a new composite material (Ti₃C₂ QDs/Fe-NC), and its microstructure and composition were analyzed by technology. The proposed material can detect acetaminophen (PA) and P-aminophenol (4-AP) simultaneously with excellent detection performance. With the best conditions, the linear ranges and detection limits were 0.50-210.00 μM, 0.03 μM (S/N = 3) and 0.50-150.00 μM, 0.06 μM (S/N = 3) for PA and 4-AP, respectively. The sensor has lower detection limits and wider linear ranges, and can successfully detect 4-AP and PA in river water and acetaminophen tablets at the same time, showing potential practical application prospects. Especially, this study reports the modification of MOF derivatives with Ti₃C₂ QDs for the first time, which expands the application scope of Quantum Dots and MOF derivatives.

基于附着有 Ti3C2 QD 的 Fe-NC 衍生物的电化学传感器同时检测对乙酰氨基酚和对氨基苯酚。

本文采用直接水热法合成了 Ti3C2 QDs 和 Fe-ZIF-8。在高温下热解 Fe-ZIF-8，得到 Fe 纳米团簇（Fe-NC）。然后将 Fe-NC 与 Ti3C2 QDs 混合形成新的复合材料（Ti3C2 QDs/Fe-NC），并通过技术分析了其微观结构和成分。该材料可同时检测对乙酰氨基酚（PA）和对氨基苯酚（4-AP），检测性能优异。在最佳条件下，PA 和 4-AP 的线性范围和检测限分别为 0.50-210.00 μM、0.03 μM（S/N = 3）和 0.50-150.00 μM、0.06 μM（S/N = 3）。该传感器具有更低的检测限和更宽的线性范围，可同时成功检测河水和对乙酰氨基酚片剂中的 4-AP 和 PA，具有潜在的实际应用前景。特别值得一提的是，本研究首次报道了用 Ti3C2 QDs 对 MOF 衍生物进行修饰，拓展了量子点和 MOF 衍生物的应用范围。

期刊介绍： Talanta provides a forum for the publication of original research papers, short communications, and critical reviews in all branches of pure and applied analytical chemistry. Papers are evaluated based on established guidelines, including the fundamental nature of the study, scientific novelty, substantial improvement or advantage over existing technology or methods, and demonstrated analytical applicability. Original research papers on fundamental studies, and on novel sensor and instrumentation developments, are encouraged. Novel or improved applications in areas such as clinical and biological chemistry, environmental analysis, geochemistry, materials science and engineering, and analytical platforms for omics development are welcome. Analytical performance of methods should be determined, including interference and matrix effects, and methods should be validated by comparison with a standard method, or analysis of a certified reference material. Simple spiking recoveries may not be sufficient. The developed method should especially comprise information on selectivity, sensitivity, detection limits, accuracy, and reliability. However, applying official validation or robustness studies to a routine method or technique does not necessarily constitute novelty. Proper statistical treatment of the data should be provided. Relevant literature should be cited, including related publications by the authors, and authors should discuss how their proposed methodology compares with previously reported methods.
