Lanthanide-potassium complex as CO2 reducer

Researchers from INAC successfully used a lanthanide-potassium complex as a catalyst to reduce CO2. The carbon-oxygen bonds were no match for the bimetal complex, and the carbonates and oxalates produced in the reaction can both be used to synthesize other chemical substances. Plus, they are released efficiently—meaning that they do not contaminate the catalyst, which can then be reused. Finally, the complex is also effective at reducing CS2 (carbon disulfide).
This initial successful experiment is part of today’s far-reaching research on CO2 reduction. Scientists around the world are exploring various approaches in efforts to uncover the “Holy Grail”—the perpetual recycling of CO2 into CH4 (methane) or other hydrocarbons.
