Pyrolytic Synthesis of Carbon Nanotubes on Ni, Co/MCM-41 Catalysts
  Process of vapor pyrolytic deposition of carbon on nickel and cobalt-containing ordered mesoporous MCM-41 matrices at decomposition of acetylene have been investigated. Formation of nanotubes, nanowires and amorphous carbon particles depending pyrolysis conditions is observed.
