Product Description:
As a unique molecular complex, NH3BH3 (AB) was made by Shore in the U.S. rocket high energy fuel program in the 1950s. In recent years, as energy shortages have worsened, ammonia borane has attracted interest because of their high hydrogen storage density (one of the most abundant hydrogen storage materials for chemical hydrides). As a potential solid hydrogen storage material, AB has the following characteristics compared with other hydrogen storage materials: firstly, AB has a hydrogen storage mass fraction of up to 19.6 wt%, it is solid at normal temperature and pressure, it’s also stable, non-flammable and non-explosive, and highly soluble in water. Borane ammonia complex is a potential hydrogen storage material with good development prospect. Due to the development of hydrogen economy, borane ammonia complex has attracted attention because of its stable hydrogen storage capacity. Its hydrogen content reached 19.6%, far exceeding the 5.5% standard set by the U.S. department of energy (DOE) in 2015.

Product Application:
In hydrogen economy, borane ammonia complex can be used as an alternative hydrogen source or hydrogen storage material for motor vehicles. The application of borane ammonia complex in fuel cells can be realized by finding an appropriate method for hydrogen release, making the hydrogen release rate controllable and the hydrogen release condition mild, and meeting the requirements of vehicle-borne fuel cells.
In organic synthesis, ammonia borane is used as an airborne stable derivative of ethyl borane, and is widely used as a reducing agent because of its good selectivity.
In the hydrogen economy, ammonia borane can be used as an alternative source of hydrogen for motor vehicles or as a material for hydrogen storage, because when ammonia borane is heated, it first converges to form (NH2BH2)n and, if further heated, continues to polymerize into (NHBH)n.
In organic synthesis, ammonia borane is used as a derivative of an airborne stable ethyl borane.

97% borane ammonia complex
As a reducing agent: ammonia borane is a very important reducing agent in organic synthesis, which can reduce carbon-carbon, carbon-nitrogen, carbon-oxygen unsaturated bond and acetal group. Ammonia borane has high solubility and good stability in organic solvents, and can reduce aldehydes and ketones into corresponding alcohols. Appropriate acidic conditions are conducive to the reduction of ammonia borane. For synthesising the metallic ammonia borane: wet (usually) in THF/dry (ball mill) will get the metal hydride reacts with ammonia borane, and metal ammonia borane also is very good hydrogen storage material, relative to ammonia borane, can effectively reduce make fuel cell toxicity of boron azine to release a quantity.

98% borane ammonia complex
The 98% purity is mainly used to prepare hydrogen storage materials. Preparation of b-n materials: boron and nitrogen polymer materials, ceramics, boron nitride, electroplating applications, preparation of metal nanoparticles, etc. Ammonia borane can also be used as the precursor of the preparation of porous boron nitride, specific practices for ammonia borane by dipping method applied into mainly mesoporous silica, mesoporous carbon pore porous solid material as template, the high temperature heating, make ammonia borane, after a series of dehydrogenation reaction to the outer hard template, a porous boron nitride material may be made.
