dc.description.abstract | Copper sulfide (Cu7S4) nanoparticles were synthesized by adding ethanolic elemental sulfur solution to an aqueous solution containing Cu(II) precursor, branched polyethyleneimine (BPEI), and ascorbic acid. By varying the Cu(II) precursor used, we could control the morphology of the nanoparticles produced to be either quasi spherical (CuF2, Cu(NO3)(2), and CuSO4) or vine like nanofibers (CuCl2 and CuBr2). By comparing experimental results and conducting calculations we found that selective adsorption of Br- and Cl- onto specific crystal facets and slowing of the reaction rate owing to formation of Cu(I)-anion-BPEI complexes explain the observed change in morphology from spherical particles to vine like nanofibers. We also found that the differences in morphology of Cu7S4 nanoparticles affects the electrochemical performance of Li batteries including the nanoparticles as electrode materials. | - |
