title: Prussian blue @ platinum nanoparticles/graphite felt nanocomposite electrodes: application as hydrogen peroxide sensor.
abstract: In this study, we report a triple-component sensor fabricated by freestanding graphite felt (GF), platinum nanoparticles (Pt) and Prussian blue (PB). Pt is ultrasonically-electrodeposited on GF to increase the conductivity and to render the catalysts to the chemical deposition of PB. Cyclic voltammetric and amperometric measurements show that the double porous PB@Pt/GF sensor exhibits two pairs of well-defined redox peaks and a prominent electrocatalytic activity toward H2O2 reduction. This resulting sensor displays impressive results with regard to a low detection limit of 1.2×10(-9)M and very high detection sensitivity of 40.9Acm(-2)M(-1), using a potential work of 0.0V.
