摘要

In this paper, a thin film of tin hexacyanoferrate (SnHCF) nanoparticles as a new Prussian blueanalogue was deposited on the surface of carbon ceramic electrode (CCE) and used as a high sensitivehydrogen peroxide (H2O2) electrochemical sensor. The SnHCF film was prepared by electrochemicalderivatization of metallic Sn doped in the CCE matrix prepared by sol-gel method. The morphology ofthe SnHCF-modified CCE was characterized by scanning electron microscopy (SEM). The proposedmodified electrode exhibited sufficient mechanical and electrochemical stability and high sensitivity incompare with other electrochemical H2O2 sensors. The sensor showed a good linear response for H2O2over a concentration range 4 50 M with a detection limit of ca. 1.47 M (S/N=3), and sensitivity of-1 -2 0.588 A M cm . The quality of experimental results demonstrates the feasibility of the sensor forpractical sensing applications.
