In this study,a triple-component hydrazine sensor(PB@Ag/GF)was fabricated with freestanding graphite felt(GF),silver nanoparticles(Ag)and Prussian Blue(PB).The Ag nanoparticles were electrodeposited on GF ultrasonically(Ag/GF),and rendered the catalyst of the chemical deposition of PB.The electrode was characterized by scanning election microscopy(SEM),infrared spectroscopy(IR),X-ray diffraction(XRD),and energy-dispersive X-ray spectroscopy(EDS).The electrochemical behavior of PB@Ag/GF was measured by cyclic voltammetry and amperometric measurements.The sensor displays a prominent electrocatalytic activity toward hydrazine oxidation,with a fast response time of 2 s,a low detection limit of 4.9 × 10-7 M and very high detection sensitivity of 26.06 A·M-1·cm-2.
