Abstract

carbon nanotubes (CNTs) research has increase in recent years due to the possibility of its application in energy storage, energy conversion devices, and solid sorbent, but there is still a lot that is unknown when it comes to synthesizing CNT. In this paper we explore the relationship between the control growth parameters and the observables in the synthesis of CNT forest by chemical vapor deposition (CVD). We studied the effects of catalyst predeposited CVD and catalyst injection CVD in terms of quantity, carbon feedstock, flow rate, substrate, substrate position, as well as temperature setting to determine in a qualitatively manner their effects on CNT density, diameter, chirality and forest height.
