Abstract
Methane was catalytically decomposed to hydrogen and highly graphitic carbon nanotubes, microfibers, microballs, and nano onions. Over Mo x-Ni(Fe,Co)y-MgOz, single-walled carbon nanotubes (SWNTs) and thin-walled carbon nanotubes (TWNTs) were produced; over Ni/Y, individually separated SWNTs were generated; over La2NiO 4, multiwalled carbon nanotubes (MWNTs) were made. Over Ni/MCM-41, with the addition of benzene, the carbon microballs (CMBs) were produced. Over Fe-Cr alloy and LaNi0.9Co0.1O3, the carbon nano onions (CNOs) and carbon microfibers (CMFs) were produced, respectively. The methane conversion efficiency and carbon growth rate followed the order: CNOs > CMBs > CMFs > MWNTs > TWNTs > SWNTs. © 2014 Copyright Taylor & Francis Group, LLC.
