A new carbon capture chemistry of carbon nanotube production

A new chemistry of carbon capture is presented, encompassing the transition metal nucleated molten carbonate splitting of CO 2 . The present series of inventions relates to a decarbonization system, process, and apparatus for producing a portfolio of different CNTs and nanomaterials and their production using CO 2 as the reactant, which is transformed by electrolytic splitting in molten carbonate electrolytes, such as Li 2 CO 3 , or in a more advanced forms by less expensive non-lithium carbonates. CO 2 is added to a molten carbonate, such as Li 2 CO 3 , and the molten carbonate is subjected to electrolysis by passing current from an anode to a cathode. A transition metal nucleation agent is added to resulting in nucleation sites that grow carbon nanomaterials at the cathode. This decarbonization process splits CO 2 , which separates into oxygen at the anode, and carbon nano-materials at the cathode. US patent 10730751i is for the system and process, while US patent 11402130 is for the apparatus, including driving the process by solar and other energy forms. Other patents apply this process to the formation of specialized carbon nanotubes, such as helical, magnetic, thin, long (wool), doped, open core knotted (nano-bamboo), closed core beaded (nano-pearl), macro-assembly (macroscopic organized assemblies) CNTs, and lithium-free electrolytes for Graphene-Based Nanocarbon synthesis. • These inventions are useful to produce carbon nanomaterials, such as CNTs, at low cost. • This invention is useful to remove CO 2 (a low-cost decarbonization process). • This invention is of value in mitigating climate change. • Several of these inventions inexpensively produce specialized high-purity carbon nanotubes, including helical, magnetic, thin, long (wool), nano-bamboo, nano-pearl, doped, and macro assemblies (macroscopic organized assemblies) CNTs. • The various types of CNTs (Carbon NanoTubes) are useful for applications ranging from enhanced property composites and batteries to catalysts, water treatment, and medical delivery to lubrication. • One of these inventions prepares carbon nanomaterials from less expensive carbonate electrolytes that do not contain lithium carbonate.
