金属复合材料基电化学传感器在双酚A检测中的应用研究

Recent Progress on the Application of Metal Composite-Based Electrochemical Sensors in Bisphenol A Detection

金属纳米颗粒作为电极修饰材料具有较高的电催化活性和稳定性,但该类材料存在分散性较差、易团聚等缺点。为此,通过金属纳米粒子的负载和稳定化等手段构建灵敏度高、选择性好和响应快的金属复合材料基电化学传感器成为当前的研究热点之一。本文就金属复合材料基电化学传感器的研究进展,以及其在双酚A(BPA)检测中的应用进行评述,为其今后的发展和实际应用提供参考。

Electrochemical sensor has the advantages of high sensitivity,good selectivity and portable instrument,and therefore has an important application prospect in rapid and efficient detection of Bisphenol A(BPA).As electrode modified materials,metal nanostructured materials usually have high electrocatalytic activity and stability,but they also have some problems such as poor dispersion and easy agglomeration.Therefore,it has become one of the research hotspots to fabricate metal composite-based electrochemical sensors with high sensitivity,good selectivity and fast response by means of loading and stabilizing metal nanoparticles.Herein,the research progress of metal composite-based electrochemical sensors and their applications in BPA detection are reviewed,the preparation of metal composites and the detection range,sensitivity and reproducibility of the corresponding electrochemical sensors are also emphasized for providing reference to their future development and practical application.
