Publication number: 20240010499Abstract: Apparatus for plasma synthesis of graphitic products including graphene, comprising: a plasma nozzle coupled to a reaction chamber; means for supplying a process gas to the plasma nozzle, the process gas comprising a carbon-containing species; and means for supplying radio frequency radiation to the process gas within the plasma nozzle, so as to produce a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species; wherein the plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction chamber, the cracked carbon-containing species also passes into the reaction chamber, and the cracked carbon-containing species recombines within the afterglow, so as to form graphitic products including graphene. A method of plasma-synthesising graphitic products including graphene is also provided.Type: ApplicationFiled: September 25, 2023Publication date: January 11, 2024Applicant: Levidian Nanosystems LimitedInventors: Dale Andrew PENNINGTON, Aaron Robert CLAYTON, Katarzyna Luiza JUDA, Catharina PAUKNER, Lukasz KURZEPA, Robert Henry ST.

Patent number: 10858255Abstract: A floating catalyst chemical vapor deposition system produces nanotubes. The system includes a reaction chamber, a heater for heating a nanotube-material precursor and a catalyst precursor, and an injector for injecting the precursors into the chamber. In the chamber, the catalyst precursor is pyrolysed to produce catalyst particles, and the nanotube-material precursor is pyrolysed in the presence of the catalyst particles in order to produce nanotubes. A controller controls at least one operational parameter, e.g., injection temperatures of the precursors, flow rates of carrier gases of the precursors, and a reaction temperature of the chamber and of the precursors. An injection pipe extends into the chamber to an adjustable extent in order to control the injection temperature of the catalyst precursor and/or the nanotube-material precursor.Type: GrantFiled: August 23, 2018Date of Patent: December 8, 2020Assignee: FGV Cambridge Nanosystems LimitedInventors: Krzysztof Kazimierz Koziol, Jerome Yi-Zhe Joaug, Catharina Paukner, Lukasz Kurzepa
