Impact of thermal annealing under nitrogen ambient on structural, micro-Raman, and thermogravimetric analyses of camphoric-CNT

Abstract

A systematical study of the effects on thermal annealing treatment under nitrogen ambient on the structural, micro-Raman, and thermogravimetric analyses of camphoric-carbon nanotubes (CNT) has been undertaken. Heat treatment of camphoric-CNT under nitrogen ambient was found to be an efficient technique of removing noncrystalline carbon and residual transition metal. Based on structural analysis, the heat-treated samples showed a clear view of overall camphoric-CNT structure. © 2013 M. S. Shamsudin et al.
