    Sammanfattning : Carbon nanostructures were fabricated by catalytic decomposition of acetylene ondifferently shaped palladium (Pd) nanocatalysts (nanoplates (triangle/hexagonal) andnanocubes) synthesized by an aqueous solution technique. The fabricated carbonnanostructures were investigated by transmission electron microscopy (TEM), itconsists of multi-walled carbon nanotubes (MWCNTs) together with significant numberof helical carbon nanofibers (HCNFs) and straight carbon nanofibers (SCNFs).
