AMORPHOUS NICKEL-PHOSPHORUS NANOFIBERS FOR BOROHYDRIDE ELECTRO-OXIDATION

摘要

Anodes for the direct borohydride fuel cell made of amorphous nickel-phosphorus coated on polyrn(acrylonitrile-co-methyl-acrylate) nanofibers was prepared by electrospinning and electrolessrnplating. X-ray diffraction and energy-dispersive X-ray spectroscopy confirmed that amorphousrnnickel-phosphorus was coated on the nanofibers. Scanning electron microscopy observationsrnshown the coated layer had a thickness of 60±25 nm and the nanofibers were uniformly coated.rnFour probe conductivity test shown that the amorphous nickel-phosphorus coated nanofibers werernelectrically conductive and had a conductivity of 104 S/cm. Most importantly, electrochemicalrninvestigation with cyclic voltammetry shown the electro-oxidation of borohydride on amorphousrnnickel-phosphorus nanofibers. This study demonstrated the amorphous nickel-phosphorus coatedrnnanofibers can be applied to the anode of direct borohydride fuel cell.
