摘要： Apparatus and method for plasma synthesis of carbon nanotubes couple a plasma nozzle to a reaction tube/chamber. A process gas comprising a carbon-containing species is supplied to the plasma nozzle. Radio frequency radiation is supplied to the process gas within the plasma nozzle, so as to sustain a plasma within the nozzle in use, and thereby cause cracking of the carbon-containing species. The plasma nozzle is arranged such that an afterglow of the plasma extends into the reaction tube/chamber. The cracked carbon-containing species also pass into the reaction tube/chamber. The cracked carbon-containing species recombine within the afterglow, so as to form carbon nanotubes in the presence of a catalyst.

摘要： Apparatus and method are disclosed for plasma synthesis of graphitic products including graphene. A plasma nozzle is coupled to a reaction chamber. A process gas is supplied to the plasma nozzle, the process gas comprising a carbon-containing species. Radio frequency radiation is supplied 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. 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 the graphitic products including graphene.

摘要： A floating catalyst chemical vapour deposition method for producing nanotubes, the method including: supplying a nanotube-material precursor and a catalyst precursor, heating said precursors and injecting said precursors into a heated reaction chamber containing a process gas; pyrolysing the catalyst precursor within the reaction chamber to produce catalyst particles; and pyrolysing the nanotube-material precursor within the reaction chamber in the presence of the catalyst particles in order to produce nanotubes; wherein the method further comprises controlling the size of the catalyst particles at the point of pyrolysis of the nanotube-material precursor by controlling the operational parameters of the reaction chamber and/or of the precursor supplies. A corresponding system for producing nanotubes is also provided. Further provided is an injector subsystem for attachment to a reaction chamber, the injector subsystem comprising: a first portion having a first set of injection pipes for receiving species for delivery into the reaction chamber; and an interface portion that is removably attachable between the first portion and the reaction chamber in use, the interface portion comprising at least one injection pipe arranged to receive the species provided by the first set of injection pipes and to inject said species into the reaction chamber in use; the injector subsystem being operable in use such that, with the interface portion removed, said first set of injection pipes are operable to individually inject their respective species into the reaction chamber, and with the interface portion attached, a pre-mixing chamber is defined by the interface portion in combination with the first portion, for pre-mixing the species provided by the first set of injection pipes prior to the species entering the at least one injection pipe of the interface portion.

摘要： 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.
