  • 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.

  • Fixing CO2 into value-added solid carbon such as carbon nanofibres is a promising process but poses substantial challenges. Now a tandem strategy is proposed where CO2 and water are electrocatalytically converted into syngas to subsequently form carbon nanofibres via a thermocatalytic process.

  • Tandem catalysis and tandem reactors provide unique opportunities for sustainably converting CO2 into valuable products that are not accessible by traditional catalytic processes. This Perspective discusses progress in and opportunities for developing tandem catalytic process that involve various combinations of thermocatalysis, electrocatalysis, photocatalysis, plasma catalysis and biocatalysis.
