摘要: Abstract In the present work we employed various transition metals (Cr, Mn, Fe, Co, Ni, Cu and Zn) loaded on different smectite clays (laponite montmorillonite) as catalysts in synthesis of carbon nanostructures (mainly nanotubes) report effect nature catalytic centers type aluminosilicate layers morphology, quality structure final products. Owing to their unique swelling, ion-exchange intercalation properties were easily, uniformly reproducibly with metal cations. Different homoionic forms montmorillonite laponite prepared containing first-row was carried out at 700 °C using an acetylene/nitrogen mixture. A variety analytical techniques (XRD, Raman, SEM, TEM thermal analysis) used fully characterize materials. Iron-, cobalt-, nickel- manganese-exchanged showed be effective for production nanotubes, while acetylene decomposition over copper-exchanged resulted creation spheres. The resulting hybrid systems are particularly attractive polymer reinforcing applications since combined action clay–carbon nanotubes matrixes can provide outstanding composite
