Abstract
An apparatus for use with a reactor for synthesis of nanostructures is provided. The apparatus includes a chamber having one end in fluid communication with the reactor and defining a pathway along which a fluid mixture for the synthesis of nanostructures can be injected into the reactor. The apparatus also has a tube in fluid communication with an opposite of the chamber to impart a venturi effect in order to generate from the fluid mixture small droplets prior to introducing the fluid mixture into the chamber. A heating zone is situated downstream from the tube to provide a temperature range sufficient to permit the formation, from components within the fluid mixture, of catalyst particles upon which nanostructures can be generated. A mechanism is further provided at a distal end of the chamber to minimize turbulent flow as the fluid mixture exits the chamber, and to impart a substantially laminar flow thereto. A method for synthesis of nanostructures is also provided.
