Abstract:
A method for preparing multi-wall carbon nanotubes comprising atomizing a precursor solution comprising an aromatic hydrocarbon and a carrier gas. The mixture is then injected through an ultrasonic atomization system to form atomized precursor droplets. Then by injecting the atomized precursor droplets from the top of a vertical chemical vapor deposition reactor, the droplets can then react with a reaction gas in the reactor vessel to form a film that adsorbs to a growth surface in the reactor vessel. Layer by layer multi-wall carbon nanotubes are formed. This method is repeated to form layers of the multi-wall carbon nanotubes. The nanotubes formed have an outer diameter of 10 nm-51 nm and a length to diameter aspect ratio of 7200-13200.

Claim (Index 1):
A hot-wall reactor method for making ferrocene-embedded multi-wall carbon nanotubes, comprising:\n atomizing a precursor solution comprising xylene, ferrocene and a carrier gas, wherein the precursor solution is injected through an ultrasonic atomization system comprising an atomizing nozzle, a nozzle stem, and an ultrasonic generating unit to form ultrasonic atomized precursor droplets; injecting the ultrasonic atomized precursor droplets from the top of a vertical chemical vapor deposition reactor into a preheating zone of the vertical chemical vapor deposition reactor; reacting a reaction gas with the ultrasonic atomized precursor droplets in a reaction zone of the vertical chemical vapor deposition reactor to form a film precursor that adsorbs to a growth surface in the vertical chemical vapor deposition reactor to form a layer of multi-wall carbon nanotubes comprising ferrocene particles embedded therein, wherein the reaction zone is heated with an electric furnace; and repeating the atomizing, the injecting of the ultrasonic atomized precursor molecule, and the reacting until one or more layers of the multi-wall carbon nanotubes are formed and then scraping the multi-wall carbon nanotubes from the growth surface of the vertical chemical vapor deposition reactor; wherein the multi-wall carbon nanotubes have an outer diameter of 10 nm-51 nm, a length to diameter aspect ratio of 7200-13200.
