Boron nitride nanomesh


Boron nitride nanomesh is a nanostructured two-dimensional material. It consists of a single BN layer, which forms a highly regular mesh by self-assembly after high-temperature exposure of a clean rhodium or ruthenium surface to borazine under an ultra-high vacuum. The nanomesh looks like an assembly of hexagonal pores. The distance between two pore centers is 3.2 nm, and the pore diameter is ~2 nm. Other terms for this material are boro nitrene or white graphene. The boron nitride nanomesh is stable to decomposition under vacuum, air, and some liquids and up to temperatures of 800 °C. In addition, it shows the extraordinary ability to trap molecules and metallic clusters with similar sizes to the nanomesh pores, forming a well-ordered array. These characteristics promise interesting applications of the nanomesh in areas like catalysis, surface functionalization, quantum computing, and data storage media like hard drives.

Boron nitride tubules were first made in 1989 by Shore and Dolan. This work was patented in 1989 and published in 1989 thesis (Dolan) and then 1993 Science. The 1989 work was also the first preparation of amorphous BN by B-trichloro borazine and cesium metal. Boron nitride nanotubes were predicted in 1994 and experimentally discovered in 1995.[ They can be imagined as a rolled-up sheet of h-boron nitride. Structurally, it is a close analog of the carbon nanotube, namely a long cylinder with a diameter of several to hundred nanometers and a length of many micrometers, except carbon atoms are alternately substituted by nitrogen and boron atoms. However, the properties of BN nanotubes are very different. Carbon nanotubes can be metallic or semiconducting depending on the rolling direction and radius. However, a BN nanotube is an electrical insulator with a bandgap of ~5.5 eV, independent of tube chirality and morphology. In addition, a layered BN structure is much more thermally and chemically stable than a graphitic carbon structure.
