Abstract
A gas storage material contains a metal-organic framework that includes a plurality of metal clusters and a plurality of charged multidentate linking ligands that connect adjacent metal clusters. Each metal cluster includes one or more metal ions and at least one open metal site. The metal-organic framework includes one or more sites for storing molecular hydrogen. A hydrogen storage system using the hydrogen storage material is provided.
Claims48
A gas storage material comprising a metal-organic framework, the metal-organic framework comprising:
- a plurality of metal clusters, each metal cluster comprising one or more metal ions and at least open metal site;
- and
- a plurality of charged multidentate linking ligands that connect adjacent metal clusters, wherein the metal-organic framework includes one or more sites for storing a gas, the gas comprising available electron density for attachment to the one or more sites for storing gas.
A hydrogen storage material comprising a metal-organic framework, the metal-organic framework comprising:
- a plurality of metal clusters, each metal cluster comprising one or more metal ions and at least one open metal site;
- and
- a plurality of charged multidentate linking ligands that connect adjacent metal clusters, wherein the metal-organic framework includes one or more sites for storing molecular hydrogen.
A hydrogen storage system comprising:
- a container having a storage cavity;
- a hydrogen storage material positioned within and filling at least a portion of the hydrogen storage container, the hydrogen storage material comprising a metal-organic framework, the metal-organic framework including:
- a plurality of metal clusters, each metal cluster comprising one or more metal ions;
- and
- a plurality of charged multidentate linking ligands that connect adjacent metal clusters, wherein the metal-organic framework includes at least one open metal site and having a sufficient number of accessible sites for atomic or molecular adsorption of molecular hydrogen.
A method of forming a metal-organic framework (MOF), the method comprising:
- a) combining a solution comprising a solvent and metal ions selected from the group consisting of Group 1 through 16 metals including actinides, and lanthanides, and combinations thereof with a multidentate linking ligand to form a percursor MOF;
- and
- b) removing one or more ligands from the precursor MOF to expose one or more open metal sites.
A gas storage material comprising a metal-organic framework, the metal-organic framework comprising:
- a plurality of metal clusters, each metal cluster comprising one or more metal ions and at least open accessible metal site;
- and
- a plurality of charged multidentate linking ligands that connects adjacent metal clusters, wherein the metal-organic framework includes one or more sites for storing a gas, the gas comprising available electron density for attachment to the one or more sites for storing gas.
