Abstract

Carbon nanofibers (CNF) with uniform diameter and controlled size could be prepared from catalytic decomposition of $C_2H_2$ with the catalyst treated by mechnochemical(MC) process. The distribution and size of Ni catalyst can be governed by tuning grinding time using MC process. As a result, size and structure of CNF can be controlled. The effect of grinding time to the as-grown CNF was checked. CNFs with diameter from 10-70nm can be synthesized. CNFs with bundle formation sharing one tip were found for MC treated catalyst.
