The determination of hydrogen peroxide (H₂O₂) based on electrochemical sensors is highly attractive in the fields of environmental monitoring and biosensing, however development of non‐precious metal‐based electrocatalysts with high performances remains challenging. Here, a new non‐enzymatic H₂O₂ sensor has been reported by using Fe₂P modified N,P co‐doped carbon (Fe₂P/NP‐C) materials as sensing materials. Fe₂P/NP‐C materials were synthesized by pyrolysis of polydopamine coating Fe‐based coordination polymer nanoparticles, which were obtained by direct mixing FeCl₃ and sodium hexametaphosphate at room temperature. The electrochemical tests display that Fe₂P/NP‐C‐based non‐enzymatic H₂O₂ sensor exhibited detection limit of 60 μM and linear range from 0.1 mM to 1 mM, respectively. This work presents a new avenue to design of non‐precious metal‐based electrocatalysts for chemical sensing and biosensing applications.

痕量Fe2P修饰N，P共掺杂碳材料的制备及其在过氧化氢检测中的应用

基于电化学传感器的过氧化氢（H ₂ O ₂）的测定在环境监测和生物传感领域具有很高的吸引力，然而，开发高性能的非贵金属基电催化剂仍然具有挑战性。在这里，已经报道了一种新的非酶促H ₂ O ₂传感器，该传感器使用Fe ₂ P改性的N，P共掺杂碳（Fe ₂ P / NP-C）材料作为传感材料。Fe ₂ P / NP‐C材料是通过聚多巴胺涂层的Fe基配位聚合物纳米颗粒的热解合成的，这些纳米颗粒是通过直接混合FeCl ₃获得的和六偏磷酸钠在室温下。电化学测试显示，基于Fe ₂ P / NP-C的非酶H ₂ O ₂传感器的检测极限分别为60μM和0.1 mM至1 mM的线性范围。这项工作为设计用于化学传感和生物传感应用的非贵金属基电催化剂提供了一条新途径。
