In this paper, TiC 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 TiC QDs to form a new composite material (TiC 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 TiC QDs for the first time, which expands the application scope of Quantum Dots and MOF derivatives.

基于附着 Ti3C2 量子点的 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


本文通过简单的水热法合成了 TiC QD 和 Fe-ZIF-8。 Fe-ZIF-8在高温下热解得到Fe-纳米簇(Fe-NC)。然后将Fe-NC与TiC QDs混合形成新型复合材料(Ti​​C QDs/Fe-NC)，并对其微观结构和成分进行技术分析。该材料可以同时检测对乙酰氨基酚（PA）和对氨基苯酚（4-AP），具有优异的检测性能。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，能够成功同时检测河水和对乙酰氨基酚片中的4-AP和PA，展现出潜在的实际应用前景。特别是，该研究首次报道了TiC量子点对MOF衍生物的修饰，拓展了量子点和MOF衍生物的应用范围。
