Method for releasing hydrogen from ammonia borane
A method of releasing hydrogen from ammonia borane is disclosed. The method comprises heating an aqueous ammonia borane solution to between about 80-135° C. at between about 14.7 and 200 pounds per square inch absolute (psia) to release hydrogen by hydrothermolysis.
1. A method of releasing hydrogen from ammonia borane, the method comprising:
heating a composition consisting essentially of an aqueous ammonia borane solution, wherein the aqueous ammonia borane solution includes at least about 43 weight percent ammonia borane in water.
2. The method of claim 1 , wherein the aqueous ammonia borane solution includes between about 43 weight percent to about 77 weight percent ammonia borane in water.
3. The method of claim 1 , wherein the aqueous ammonia borane solution is heated to at least 80° C., wherein hydrogen release takes place.
