Covalent triazine framework/carbon nanotube hybrids enabling selective reduction of CO2 to CO at low overpotential

Nitrogen-rich covalent triazine frameworks (CTFs) were grown in situ onto surface-functionalized carbon nanotubes. These novel hybrid catalysts electrochemically reduce CO₂ to CO with a faradaic efficiency up to 81% at an overpotential of 380 mV.
