Carbon nanotube synthesis via ceramic catalysts


Abstract:

The potential for ceramics as catalysts for carbon nanotubes (CNTs) formation exceeds that of metal catalysts in that ceramics can serve not only as a catalyst particle for CNT nucleation/growth as found with metal catalysts, but they can also serve as a template for the synthesis of carbon nano-structures. They can also be purified more readily. Here we present studies on the growth of CNTs from ceramics in laser pyrolysis and chemical vapor deposition (CVD) routes. We show CNT growth from both nanowires and ceramic particles. In addition, doping of the CNTs can also be achieved through the use of ceramic catalysts. Since ceramic materials are easily removed from the as-produced samples as compared to metal catalysts, they are attractive for further application, e.g., in carbon-based electronics. © 2009 WILEY-VCH Verlag GmbH & Co.
