英文摘要	novel pd-ni alloy nanoparticle/carbon nanofiber (pd-ni/cnf) composites were successfully prepared by a simple method involving electrospinning of precursor polyacrylonitrile/pd(acac)(2)/ni(acac)(2) nanofibers, followed by a thermal process to reduce metals and carbonize polyacrylonitrile. the nanostructures of the resulting pd-ni/cnf nanocomposites were carefully examined by a combination of scanning electron microscopy (sem), transmission electron microscopy (tem), high resolution transmission electron microscopy (hrtem), high-angle annular dark field (haadf)-scanning transmission electron microscopy (stem), energy dispersive x-ray (edx), thermogravimetric analysis (tga), x-ray diffraction (xrd), and x-ray photoelectron spectra (xps). for all the nanocomposites, the pd-ni alloy nanoparticles (nps) were dispersed uniformly and embedded firmly within the framework or on the surface of cnf. the size, composition, and alloy homogeneity of the pd-ni alloy nps could be readily tailored by controlling the feed ratio of metal precursors and the thermal treatment process. cyclic voltammetric studies showed enhanced redox properties for pd-ni/cnf-based electrodes relative to the ni-metal electrode and significantly improved electrocatalytic activity for sugar (e.g., glucose, fructose, sucrose, and maltose) oxidation. the application potential of pd-ni/cnf-based electrodes in flow systems for sugars detection was explored. a very low limit of detection for sugars (e.g., 7-20 nm), high resistance to surface fouling, excellent signal stability and reproducibility, and a very wide detection linear range (e.g., 0.03-800 mu m) were revealed for this new type of pd-ni/cnf nanocomposite as the detecting electrode. such detection performances of pd-ni/cnf-based electrodes are superior to those of state-of-the-art nonenzymatic sugar detectors that are commercially available or known in the literature.
