摘要：
Electrospun carbon nanofibers modified with Pd sensors have been developed for O-2 sensing with high sensitivity. The average diameter of carbon nanofiber and Pd particle is about 251 and 20.5 nm, respectively. The sensing performances of the Pd decorated carbon nanofiber (Pd-CNF) electrode towards reduction of O-2 were evaluated. The Pd-CNF electrode with a Pd loading of 4.7 mg/cm(2) shows maximum sensitivity of 2.6 mu Appm(-1)cm(-2) in the O-2 concentration region of 100-1000 ppm. The response and recovery times are less than 32 and 48 s, respectively. The high sensitivity, wide linear range and rapid response and recovery times make the Pd-CNF electrode a promising candidate for amperometric O-2 sensors.
