近年来,各种新污染物因其潜在的毒性,对生态环境、生物体、人体健康造成了严重的威胁,已经被越来越多的研究者所关注。 尽管传统的检测方法具有较高的灵敏度与准确性,但它们往往依赖于大型且昂贵的检测设备以及复杂的操作过程。 因此,对新污染物进行快速、精确、便捷的检测是环境污染防控的一个重要环节。 在众多检测方法中,光电化学(PEC)传感器因其较低的背景信号,良好的灵敏度以及易于小型化等优点成为了新污染物检测领域的研究热点之一。本文系统详细的综述了 PEC 传感器的检测机理及其在新污染物检测领域的应用研究。 介绍了目前 PEC 传感器常用的检测策略、识别策略、以及光电活性材料的改性策略。 讨论了 PEC 对多类新污染物检测的研究进展。 最后,对 PEC 传感器在新污染物检测领域的发展给出了一些建议和展望,提出了一些潜在的问题与可能的改进方法,以促进 PEC 传感器在新污染物检测领域的进一步发展与应用。

In recent years,various emerging contaminants have caused serious threats to the ecologicalenvironment,organisms,and human health due to their potential toxicity,which have attracted more andmore attention by researchers. Although traditional detection methods have high sensitivity and accura⁃cy,they often rely on large and expensive detection equipment and complex operational procedures.Therefore,rapid,accurate,and convenient detection of emerging contaminants is an important link in theprevention and control of environmental pollution. Among many detection methods,the photoelectro⁃chemical (PEC) sensors have become one of the research hotspots in the field of emerging contaminantdetection due to its advantages of low background signal,good sensitivity,and easy miniaturization. Thispaper systematically reviews the detection mechanism of the PEC sensors and their applications in thefield of emerging contaminant detection. The detection strategies,identification strategies of PEC sen⁃sors,and modification strategies of photoelectric active materials used in PEC sensors are introduced.The research progress of PEC for the detection of many kinds of emerging contaminants is discussed. Fi⁃nally,some suggestions and prospects for the development of PEC sensors in the field of emerging con⁃taminant detection are put forward,and some potential problems and possible improvement methods areproposed to promote the further development and application of PEC sensors in the field of emergingcontaminant detection.
