| When the solvent is removed, nanosized pores filled with ammonia borane are left. |
| The phosphonium borate splits into H2 molecules and phosphine borane, then recombine under cooler temperatures to create the original compound. |
| To transform the ammonia borane to a nanomaterial, scientists dissolve the solid compound in a solvent and then add the solution to the mesoporous support material. |
| Capillary action of the porous material pulls the ammonia borane into the pores of the support. |
| But figuring out exactly how to regenerate ammonia borane from the residuum left after hydrogen has been extracted remains a stumbling block. |
| Electrospining concept has been used to incorporate ammonia borane core and polystyrene sheath in a nano matrix which is permeable to hydrogen. |
