Converting natural gas into hydrogen and solid carbon materials using methane pyrolysis presents a promising opportunity to produce sustainable fuels and materials. The production of hydrogen and bulk carbon nanotubes (CNTs) via methane pyrolysis has been demonstrated independently, but concurrent production from the same reactor has remained elusive. Here the authors present a multi-pass floating catalyst chemical vapour deposition (FCCVD) reactor that converts methane into hydrogen and CNT aerogel.
