✦ Synopsis
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 mM -0.26 mM with a detection limit of ca. 0.7 mM (S/N ¼ 3), and sensitivity of 754.6 mA M À1 cm À2 . This work demonstrates the feasibility of self-assembled PBNPs-modified CCE for practical sensing applications.
