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

<div>SEM images of nickel cathodes collected after 2 h of chronopotentiometry at 25 mA cm-2 in molten salt electrolytes with borate concentrations of (a) 0, (b) 3, (c) 5, and (d) 7 mol% under CO2 flow of 50 mL min-1 at 750°C (scale bar: 100 nm). SEM images of nickel cathodes prepared at current densities of (e) 10, (f) 25, (g) 50, and (h) 100 mA cm-2 for a fixed borate concentration of 3 mol% (scale bar: 1 μm).</div>
