The heterogeneity of the web by changing the ratio of cobalt to graphitic carbon in the reaction mixture is investigated. The various webs were studied by electron microscopy and micro-Raman spectroscopy. It is shown that structures in the web have varying degrees of order, and this relates to mechanism of growth. By hydrothermally oxidizing and removing the nanotubes in the web a new spherical particle was observed which by micro-Raman spectroscopy was shown to have a high degree of order.
