Large-Scale Electrosynthesis of Carbon Nano-Onions from CO2 as a Potential Replacement for Carbon Black
Graphite and carbon black are major global commodities whose production generates substantial CO _2 emissions. Carbon nano-onions (CNOs), consisting of concentric graphene spheres with enhanced properties due to their unique morphology, represent a promising next-generation material. This study pres...

| description | Graphite and carbon black are major global commodities whose production generates substantial CO _2 emissions. Carbon nano-onions (CNOs), consisting of concentric graphene spheres with enhanced properties due to their unique morphology, represent a promising next-generation material. This study presents a scalable, low-cost, carbon-negative electrosynthesis of CNOs directly from greenhouse CO _2 . Electrolysis is performed in molten lithium and lithium/strontium carbonate mixtures near their melting points, which suppresses transition metal-catalyzed Carbon NanoTube (CNT) formation, favoring uniform CNO growth. The method offers an efficient pathway for sustainable carbon nanomaterial production and CO _2 utilization. |
