Abstract
Ammonia (NH3) has large gravimetric and volumetric H2 densities and has advantages as hydrogen and energy carriers. Unfortunately, NH3 is a deleterious substance. NH3 storage technology is essentially necessary to suppress leaked NH3 in the atmosphere. Many kinds of NH3 storage materials, which are metal halides, borohydrides, ammonia borane, proton-based materials, porous materials and water have been studied. In those materials, water easily collects leaked NH3 because of the large diffusion coefficient of NH3. H+ in proton-based materials can react with lone electron pair of NH3 to form NH4+ and has low NH3 vapor pressure in the atmosphere. Insoluble proton-based materials also can remove nitrogen (NH3–N) from NH3 water. Therefore the NH3 removal system combined water and insoluble proton-based materials will be candidate for the leaked NH3 concentration lowering in the atmosphere by suppression of water pollution.
