Selective and efficient synthesis of thin carbon nanofibers (CNF) of fish bone-like texture with diameter below 40 nm was shown at low temperatures (673-873 K) from an ethylene and hydrogen (4:1) mixture, using Ni-Fe alloys supported on carbon blacks of relatively small surface area. A particular alloy of a Ni-Fe (8:2 w/w) was highly dispersed to produce thinner fibers at 753 K than Ni alone or Ni-Fe...
Several basic metal-containing carbon xerogels (Na, K, Mg, and Zr) were obtained by polymerisation of resorcinol with formaldehyde in the presence of metallic precursors. A blank sample was also prepared without any metal addition. The carbonised derivatives were obtained by pyrolysis of the xerogels in nitrogen at 1000 o C. The samples were characterised by different techniques including...
