General description
Ammonia borane, also known as borazane has high hydrogen content (about 20% mass). Thermal decomposition of borazane takes place in the temperature range of 350-410K accompanied by hydrogen release and heat evolution. It may find use as a hydrogen source in fuel cells in the future.[1]
Borane-ammonia complex is a novel material, where ammonia is tightly bound to a ligand through all four of its atoms. It is a donor-acceptor complex that is formed by electron donation from a Lewis base (NH3) to a Lewis acid (BH3). It shows a B-N bond distance of 1.564 Å.[2][3]

Application
Borazane acts as a mild, efficient, and stereoselective reducing agent for aldehydes and ketones in protic or nonprotic media.[4][5]It can be used as a storage medium for release of hydrogen[6][7]Borazane is popularly used as an ammonia borane (AB) source for the formation of hexagonal boron nitride monolayers which are used as a substrate for graphene growth.[8][9][10][11]

Hexagonal boron nitride (h-BN) is a promising dielectric material for graphene-based electronic devices. Here we investigate the potential of h-BN gate dielectrics, grown by chemical vapor deposition (CVD), for integration with quasi-freestanding epitaxial graphene (QFEG). We discuss the large scale
