In particular, iron, cobalt, and nickel were investigated for SWNTs synthesis. Iron was found to grow better-quality SWNTs compared to cobalt and nickel. To study the effect of catalyst supports, magnesium oxide, silicon oxide, and aluminium oxide were chosen for iron. Among the studied supports, MgO was identified to be a suitable support for iron as it produced SWNTs with better graphitisation determined by Raman analysis. Increasing the iron loading decreased the quality of SWNTs due to extensive agglomeration of the iron particles. Thus, lower metal loading percentage is preferred to grow better-quality SWNTs with uniform diameters. 2014-04-25T03:20:26Z 2014-04-25T03:20:26Z 2013 Article Journal of Nanomaterials, vol. 2013, 2013, pages 1-8 1687-4110 http://www.hindawi.com/journals/jnm/2013/592464/ http://dspace.unimap.edu.my:80/dspace/handle/123456789/34046 en Hindawi Publishing Corporation |
