The excessive use of pesticides in agricultural or non-agricultural fields causes the emergence of environmental and human health problems. Therefore, there is a need to develop simple, fast, sensitive, selective, and low-cost methods for analyzing pesticides from different matrices. Although many analysis methods have been developed to determine pesticides, nanomaterial-based electroanalytical methods offer numerous advantages such as rapid and low cost of analysis, low sample volume requirement, field deployability, and miniaturization to improve the performance of the developed methods. Among different nanomaterials, bimetallic nanomaterials such as gold, platinum, palladium, nickel, and iron-based nanomaterials in combination with other metals have been extensively used as electrode modification agents due to their electrocatalytic characteristics and the synergistic effect of two metals. In this review, firstly, the basic information of pesticides and bimetallic nanomaterials was summarized. Properties, synthesize, and architectures of bimetallic nanomaterials and their nanocomposites were explained in detail. Current applications and utilization of bimetallic nanomaterials for pesticides detection were reviewed by selected studies with working range, the limit of detection, sensitivity, analytical application, and some experimental conditions. In conclusion, the current challenges and future trends for analyzing pesticides based on electroanalytical methods combined with bimetallic nanomaterials were highlighted.

在农业或非农业领域过度使用农药导致环境和人类健康问题的出现。因此，需要开发简单、快速、灵敏、选择性和低成本的方法来分析来自不同基质的农药。尽管已经开发了许多分析方法来测定农药，但基于纳米材料的电分析方法具有许多优点，例如分析快速且成本低、样品量要求低、可现场部署和小型化，以提高所开发方法的性能。在不同的纳米材料中，双金属纳米材料如金、铂、钯、镍、由于其电催化特性和两种金属的协同作用，铁基纳米材料与其他金属结合被广泛用作电极改性剂。在这篇综述中，首先总结了农药和双金属纳米材料的基本信息。详细解释了双金属纳米材料及其纳米复合材料的性质、合成和结构。从工作范围、检测限、灵敏度、分析应用和一些实验条件等方面对双金属纳米材料在农药检测中的应用和利用进行了综述。总之，强调了基于电分析方法结合双金属纳米材料分析农药的当前挑战和未来趋势。
