Storage and delivery veseel for storing GeH4, using a zeolitic adsorbent

A storage and dispensing vessel enclosing an interior volume that contains zeolitic imidazolate framework adsorbent, and GeH4 adsorbed on the adsorbent, the vessel comprising:

• a port;
• a valve mounted at the port;
• zeolitic imidazolate framework adsorbent within the interior volume;
• and
• GeH4 adsorbed on the zeolitic imidazolate framework;
• the vessel being selectively actuatable to flow gaseous GeH4 from the interior volume of the vessel, through the valve, for discharge of the GeH4 from the vessel;
• and
• wherein the amount of degradation of GeH4 to hydrogen gas (H2) is less than 1 percent of total initial adsorbed germane, over a period of 365 days, at 30 degrees Celsius;
• and
• a storage capacity for the GeH4 of at least 100 g/kg.
