Microwave Synthesis of Boron Nitride Nanostructures

چکیده
One dimensional boron nitride nanostructures promise many interesting applications in biomedical, semiconductor and hydrogen storage and other fields. We have synthesized Boron Nitride in various nanoforms by a high temperature solid state reaction between boric acid and urea in a commercial microwave furnace. The formation of boron nitride was established from the binding energies for boron and nitrogen obtained from its X-Ray Photoelectron spectrum. The structural phase of the product was confirmed by X-Ray diffraction and Fourier Transform Infrared spectroscopy. Transmission Electron Microscopy revealed that BN nanowires of about 20 nm diameter with very high aspect ratios of the order of 100:1 and also nanotubes were obtained.
