Synthesis, characterization, and purification of boron nitride nanotubes intercalated with magnesium

Abstract

Intercalation of Boron Nitride Nanotubes (BNNTs) with magnesium (Mg) is explored due to its potential super-conductive properties. Various syntheses were performed under different sets of conditions in order to optimize reaction conditions. These include the presence of zinc as a catalyst and the temperature at which the reaction is carried out (either 700 or 800°C). All products were then analyzed and characterized, using methods such as Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM), Energy-dispersive X-ray Spectroscopy (EDX), and Fourier-Transform Infrared Spectroscopy (FTIR). Both TEM and FTIR results confirmed the formation of BNNTs, and EDX showed the presence of magnesium in the product, indicating possible intercalation with Mg. A purification method for the crude product was established, and the purified product was further characterized. Results indicated the tubes became clearer after purification, however, some impurities remain. Purification methods must be further investigated.
