Isotope separation

Nitrogen-doped tin catalysts lift carbon-13 in CO2 electrolysis from 1.1% to over 14%

Researchers using nitrogen-doped tin catalysts in CO2 electrolysis raised carbon-13 from its natural 1.1% to over 14% of the output CO2. A computed isotope factor guided the catalyst choice, though the energy saving over existing separation methods is still to be measured.
