Nucleation-Controlled Production of Sub-50 nm Carbon Nanotubes through Electrochemical Conversion of Carbon Dioxide in Carbonate Molten Salt

<div>(a) Schematic of chemical reactions in the molten salt-based CO2 electrolysis. (b) Cyclic voltammograms of the Ni working electrode measured for different borate concentrations at a scan rate of 10 mV s-1. The (c) potential and (d) CO concentration monitored during 2 h of chronopotentiometry at current densities of 25, 50, and 100 mA cm-2 and a borate concentration of 3 mol%. (e) FEs for CO and carbon production at different current densities for a borate concentration of 3 mol%. (f) The effect of borate concentration on the FE at a current density of 25 mA cm-2.</div>
