Structure of Carbon Nanotubes Synthesized by Ethylene Decomposition Over Cobalt Supported on Basic Oxides
Autor: N. V. Lemesh, A. I. Tripolsky
Publikováno v: Theoretical and Experimental Chemistry. 50:299-303
A study was carried out on the structure of carbon nanotubes obtained on coprecipitated Co/MgO and Co/CaO catalysts. Regardless of the nature of the basic support, the use of cobalt catalysts leads to the formation of cylindrical nanotubes with ident
