Abstract
A material for the storage and release of gases comprises a plurality of hollow elements, each hollow element comprising a porous wall enclosing an interior cavity, the interior cavity including structures of a solid-state storage material. In particular examples, the storage material is a hydrogen storage material, such as a solid state hydride. An improved method for forming such materials includes the solution diffusion of a storage material solution through a porous wall of a hollow element into an interior cavity.
Claims19
A method of preparing a material allowing storage and release of a gas, the method comprising:
- providing a hollow glass element having a porous wall enclosing an interior cavity, the porous wall having an interior surface facing the interior cavity;
- introducing a gas storage material into the interior cavity by diffusion of a solution through the porous wall, the solution being a solution of the gas storage material in a solvent;
- and
- removing the solvent from the interior cavity to form nano-scale crystal structures of the gas storage material within the interior cavity, thereby preparing the material allowing storage and release of the gas,
- the nano-scale crystal structures being needle crystals of the gas storage material grown from the interior surface of the porous wall,
- the gas being hydrogen,
- the gas storage material being a solid metal hydride.
