EPFL team develops low-cost catalyst for splitting CO2

Green Car Congress

EPFL scientists have developed an Earth-abundant and low-cost catalytic system for splitting CO 2 into CO and oxygen—an important step towards achieving the conversion of renewable energy into hydrocarbon fuels. A solar-driven system set up using this catalyst was able to split CO 2 with an efficiency of 13.4%.

GWU team demonstrates highly scalable, low-cost process for making carbon nanotube wools directly from CO2

Green Car Congress

The process is constrained by the (low) cost of electricity. Larger scale C2CNT can be achieved through direct elimination of atmospheric CO 2 using solar heat and solar to electric PVs. Monel cathode substrates, electrolyte equilibration, and a mixed metal (NiChrome) nucleation facilitate the synthesis of this CNT wool.
