In this study, in order to promote the catalytic abilities of CFP, the electrodeposition of palladium nanoparticles (Pd NPs) has adopted to improve the electrochemical characteristics on the surface of CFP. The Pd-based CFP electrodes are optimized to sense or react with specified molecules. The catalytic reaction of hydrogen peroxide is explored by cyclic voltammetry (CV) and the oxidative current is 33.26 μA. In addition, the oxidation reaction of ethanol in alkaline media is also demonstrated by CV. PdNP/CFP electrode exhibits a peak current and current density of 81.2 mA and 541.32 mA cm-2 (or 68.22 mA mg-1 Pd), respectively. Moreover, the morphologies and distribution of Pd NPs on CFP are the factors to affect the catalytic properties. Through the optimal modification on the surface of CFP, we expect it could be applied in the development of biosensor and fuel cell.
