Upgrading biogas to valuable solid carbon can potentially lead to negative CO2 emissions with long-term carbon storage but faces substantial thermodynamic and kinetic limits using a single reactor. Tandem strategies can decouple reactions into tandem reactors, integrate non-equilibrium processes and identify synergistic catalytic sites to enhance carbon nanofiber production.
