摘要：
In this paper, successful structural transformation of carbon black (CB) into nanotubes and nano-onion like structures at relatively low temperatures in the presence of transition metal catalyst is reported. This study focuses also on the influence of the temperature on the structural transformation of CB into nanostructures. The experiments were carried out at 700 degrees C and 1000 degrees C in a horizontal tube furnace under N-2 atmosphere. The obtained samples were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HRTEM). It was found that increase in the synthesis temperature from 700 degrees C to 1000 degrees C influences the morphology of the produced nanotubes significantly and the degree of crystallinity also increased with the temperature..
