The determination of hydrogen peroxide (H 2 O 2 ) 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 H 2 O 2 sensor has been reported by using Fe 2 P modified N,P co‐doped carbon (Fe 2 P/NP‐C) materials as sensing materials. Fe 2 P/NP‐C materials were synthesized by pyrolysis of polydopamine coating Fe‐based coordination polymer nanoparticles, which were obtained by direct mixing FeCl 3 and sodium hexametaphosphate at room temperature. The electrochemical tests display that Fe 2 P/NP‐C‐based non‐enzymatic H 2 O 2 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.
