Surface| Summary: | The effect of the chemical nature of the support of the Ni-, Co- and Fe-containing catalysts deposited by impregnation method on MgO, CaO and CaCO3 on structure of carbon nanotubes synthesized over them from the  ethylene was investigated. It is shown that the catalysts deposited on magnesium oxide produced carbon nanotubes with the lowest diameters and most uniform diameters and morphology, due to the strong interaction of metal with the support. The use of catalysts with CaO and CaCO3 supports leads to the formation of different types of carbon nanotubes by diameters and morphology and with nanofibers impurities that caused predominantly by the interaction between the metal and support. |
