Transmission Electron Microscope (TEM) Observation of Catalyst Particles at the Tip of Carbon Nanocoils

Abstract

The morphology of the carbon nanocoils (CNCs) and their catalyst particles were characterized by a transmission electron microscope (TEM) to discuss the growth mechanism of CNCs. The catalyst particles of CNCs have many corner numbers on TEM images. This means that the catalyst particles of CNCs have several facets. In this study, the growth mechanism of CNCs was discussed at the point of the different velocities of the carbon extrusion from these facets.
