Carbon Dioxide Mitigation: Carbon Nano‐Onions Made Directly from CO₂ by Molten Electrolysis for Greenhouse Gas Mitigation (Adv. Sustainable Syst. 10/2019)

In article number 1900056, Stuart Licht and co-workers, the first high yield electrosynthesis of carbon nano-onions (CNOs) by low cost molten carbonate electrolysis is shown. The only reactant, CO2, becomes a useful, valuable resource rather than a greenhouse pollutant as a response to mitigate anthropogenic CO2. The synthesis is achieved by excluding nucleating agents from the molten carbonate growth medium resulting in a profusion of uniform CNOs.
