摘要：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 x 10(-9) M and very high detection sensitivity of 40.9 A cm(-2) M-1, using a potential work of 0.0 V.
