Anodic Aluminum Oxide Cylindrical Wall Supported Toroidal Catalyst and Segregated Flow Reactor for Continuous Nanotube Growth

摘要

A method includes providing a substrate including a tube with a first opening a second opening, depositing a metal film onto a portion of the tube near the first opening, and growing a carbon nanotube by passing a carbon-based gas through the tube and metal film. The gas enters the tube through the second opening and exits the tube through the first opening.

1. A method comprising:
providing a substrate, the substrate comprising:
a first surface,a second surface opposite the first surface, anda tube with a first opening at the first surface and a second opening at the second surface; depositing a catalyst onto a portion of the tube near the first surface; and growing a nanotube, comprising passing a carbon-based gas through the tube, the carbon-based gas entering the tube through the second opening and exiting the tube through the first opening.
