"A molecular dynamics simulator coupled to a quantum semiempirical Hamiltonian model was applied to multiscale modeling of the catalytic decomposition of hydrocarbons during carbon nanotube (CNT) and carbort nanofiber (CNF) growth. It was found that catalytic decomposition of acetylene is accompanied by a large energy release and its rate weakly depends on temperature in the range from 20 to 700 C. In contrast, the methane decomposition rate substantially decreases as the iron temperature drops," investigators in the United States report.
"A comparative analysis of acetylene decomposition on a clean surface and on an oxidized Fe(100) surface showed that the ...
