Description
Summary:Due to the axial ratio feature, bimetallic nanofibers are expected to have novel characteristics. In this study, Pd-doped Co nanofibers could be successfully prepared using simple, low cost, high yield and effective technique; electrospinning. The introduced nanofibers have been synthesized by calcination of electrospun nanofibers composed of Pd NPs/cobalt acetate tetrahydrate/poly(vinyl alcohol) in a vacuum atmosphere. The introduced Pd–Co nanofibers revealed distinct photocatalytic activity as an almost 90% from the methylene blue dye has been oxidized within 30min. As an active layer in a diode, the introduced nanofibers showed good performance. Magnetic properties study indicated that Pd nanoparticles negatively affected the saturation magnetization of the cobalt nanofibers, however very low remenant magnetization was obtained (7.7emu/g) compared to the un-doped Co nanofibers (69.22emu/g) which concludes that Pd modified Co to be magnetically clean material. [Display omitted] ► Pd-doped cobalt nanofibers were synthesized using simple and effective technique. ► The ntroduced nanofibers revealed distinct photocatalytic activity. ► The introduced nanofibers can be used as an active layer in the diodes. ► The introduced nanoifibers are magnetically clean material.
