Abstrak

Electrospun carbon nanofibers modified with Pd sensors have been developed for O2 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 O2 were evaluated. The Pd-CNF electrode with a Pd loading of 4.7 mg/cm2 shows maximum sensitivity of 2.6 μAppm-1cm-2 in the O2 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 O2 sensors.
