Method for continuous production of catalysts for synthesis of carbon nanotubes

Abstract

A new method for continuous production of carbon nanotube (CNT) catalysts is proposed in this study. The method is a modification of the solution combustion synthesis and was called continuous solution combustion synthesis (CSCS). The method consists of the atomization of the modified combustion synthesis precursor solution in a pilot flame. A combustible, like ethanol, is added to the precursor solution to improve the evaporation of the solvent and the atomization. The ignition of the precursor solution is selfsufficient. A fine and porous powder is produced. The powder, collected through an electrostatic precipitator, has superior performance as a carbon nanotube catalyst. When comparing the production of Fe -Mo/MgO catalyst synthesized by the continuous method with the conventional route, it was observed that the amount of carbon nanotubes increased by 52 wt%, and the G/D ratio was also higher.

“…This technique has been also widely used to produce novel nanomaterials . Lima et al synthesized Fe–Mo/Mg catalysts used in single‐walled carbon nanotube production by solution combustion synthesis, using both batch and continuous modes of operation. The efficient SHS production of silicon carbide nanowires (SiCNWs) has been also reported by Huczko et al .…”

“…Several methods, such as screen printing, direct synthesis on a substrate, and electron deposition, can be used to fabricate CNT cathodes. [7][8][9] The screen printing method is a simple method that can be used for mass production. It can be used to fabricate products with large areas.…”
