In this paper, self‐assembled Prussian blue nanoparticles (PBNPs) on carbon ceramic electrode (CCE) were developed as a high sensitive hydrogen peroxide (H 2 O 2 ) electrochemical sensor. The PBNPs film was prepared by a simple dipping method. The morphology of the PBNPs‐modified CCE was characterized by scanning electron microscopy (SEM). The self‐assembled PB film exhibited sufficient mechanical, electrochemical stability and high sensitivity in compare with other PB based H 2 O 2 sensors. The sensor showed a good linear response for H 2 O 2 over the concentration range 1 μM–0.26 mM with a detection limit of ca. 0.7 μM ( S / N =3), and sensitivity of 754.6 mA M −1 cm −2 . This work demonstrates the feasibility of self‐assembled PBNPs‐modified CCE for practical sensing applications.
