The beneficial effect of CO2 in the low temperature synthesis of high quality carbon nanofibers and thin multiwalled carbon nanotubes from CH4 over Ni catalysts

A low temperature chemical vapor deposition method is described for converting CH₄ into high-quality carbon nanofibers (CNFs) using a Ni catalyst supported on either spinel or perovskite oxides in the presence of CO₂. The addition of CO₂ has a significant influence on CNF purity and stability, while...
