Abstract

We report a systematic evaluation of the influence of the use of nitric acid at elevated temperature (80°C) as purification and functionalization treatment for four different types of multi wall carbon nanotubes (MWCNTs) and for carbon microparticles upon their physico-chemical properties. We used BET, Raman spectroscopy, high resolution X-ray photoelectron spectroscopy and electrochemical impedance spectroscopy measurements for MWCNTs characterization. We found that nitric acid treatment significantly changes physico-chemical properties of MWCNTs and that these changes vary significantly between different MWCNTs. Therefore we urge researchers to be careful when relying on the physico-chemical properties measured on different MWCNTs samples.
