“…For example, BCl 3 was not used because it is highly reactive; instead, solid boron precursors and catalyst were utilized in a solid-solid reaction process in flowing inert gas. First, 50 wt% MgB 2 (Alfa Aesar), 30 wt% nano-NiB (prepared in a manner following [22,23]), and 20 wt% of mesostructured hexagonal framework MCM-41 zeolite powder (Sigma-Aldrich) are mixed and reduced in particle size by grinding using a mortar and pestle. Typically, 0.02-0.1 grams of the mixture was added and ground in an agate mortar for about an hour to ensure that the powder was well mixed.…”

The synthesis of boron nanowires, nanotubes, and nanosheets using a thermal vapor deposition process is reported. This work confirms previous research and provides a new method capable of synthesizing boron nanomaterials. The materials were made by using various combinations of MgB2, Mg(BH4)2, MCM-41, NiB, and Fe wire. Unlike previously reported methods, a nanoparticle catalyst and a silicate substrate are not required for synthesis. Two types of boron nanowires, boron nanotubes, and boron nanosheets were made. Their morphology and chemical composition were determined through the use of scanning electron microscopy, transmission electron microscopy, and electron energy loss spectroscopy. These boron-based materials have potential for electronic and hydrogen storage applications.

“…CVD methods for producing BN filaments and BNNTs have been utilized in several works. [35][36][37][38][39][40][41] Gleize et al 35 used diborane and ammonia or N 2 gases as the boron and nitrogen containing precursors. These were deposited on various boride surfaces ͑including Zr, Hf, Ti, V, Nb, and Ta borides͒ at a temperature of 1100°C.…”

In an attempt to understand why catalytic methods for the growth of boron nitride nanotubes work much worse than for their carbon counterparts, we use first-principles calculations to study the energetics of elemental reactions forming N 2 , B 2 , and BN molecules on an iron catalyst. We observe that the local morphology of a step edge present in our nanoparticle model stabilizes the boron nitride molecule with respect to B 2 due to the ability of the step edge to offer sites with different coordination simultaneously for nitrogen and boron. Our results emphasize the importance of atomic steps for a high yield chemical vapor deposition growth of BN nanotubes and may outline new directions for improving the efficiency of the method.

“…One such type is pre-treated elemental boron powders via ball-milling methods in an ammonia gas for 150 h at 1000 ºC, and then thermal annealing them under a nitrogen atmosphere at 1000 ºC [19,[57][58][59]. This method also yielded isotopic 10 BN nanotubes [60].…”
