Metal organic framework is a kind of zeolite-like material with repetitive network structure formed by self-assembly of organic ligands, inorganic ligands and metal ions. As a new type of material, metal organic framework belongs to coordination chemistry field and it is developed rapidly recently. Compared with traditional inorganic porous materials, metal organic framework has larger porosity and specific surface area. In addition, the pore size of metal organic frameworks is adjustable and they can be modified by variable functional groups. Therefore, as a new nanomaterial, metal organic framework has attracted more and more attentions.

According to the types of organic ligands, metal ions or metal ion clusters, metal organic frameworks can be divided into the following categories.
