Nucleation-Controlled Production of Sub-50 nm Carbon Nanotubes through Electrochemical Conversion of Carbon Dioxide in Carbonate Molten Salt
Figure 4
(a) The Raman spectra of CNTs prepared at current densities of 25, 50, and 100 mA cm-2 for a borate concentration of 3 mol%. (b) N2 adsorption-desorption isotherms and (c) the corresponding specific surface area of the CNT products. (d) Plot of the specific surface area vs. the CNT diameter for different CNT products. Nucleation-controlled CNTs prepared with the three current densities are denoted by NCCNT-25, NCCNT-50, and NCCNT-100, and commercial CNT products obtained through chemical vapor deposition (CVD) methods are indicated by the model and company names.
