Graphitic nanomaterials from biogas-derived carbon nanofibers

Carbon nanofibers with different microstructure and elemental composition that were produced in the catalytic decomposition of synthetic biogas mixtures, in a rotary-bed reactor using nickel and nickel-cobalt catalysts at 600 °C and 700 °C, were heat treated in the temperature interval 2600–2800 °C...
