Synthesis of Carbon Nanotubes From CO2 Enabled by Fe–Mo Bimetallic Catalysts via Effective CO2 Scavenging

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The tandem process involves CO2 methanation and CH4 pyrolysis for CNT synthesis. Unreacted CO2 and H2 from methanation oxidize Fe, suppressing CNT growth on Fe‐only catalysts. Incorporation of Mo into Fe/MgO forms Mo2C, which prevents Fe oxidation under CO2/H2 conditions and thereby enables CNT formation.
