Description
Technical Field
The invention belongs to the field of inorganic chemistry and material chemistry science, and particularly relates to a metal organic framework compound, a preparation method and application thereof in adsorption separation.
Background
Acetylene plays a role in the fields of petroleum, chemical industry, energy and the like, is an important fuel, and is also an important raw material for preparing chemical products such as rubber, fiber and the like. Acetylene is mainly derived from the pyrolysis process of petroleum and the incomplete combustion of methane, so that acetylene often contains different amounts of impurity gases such as methane and carbon dioxide. The purification of acetylene has important economic significance and value for the high-efficiency use of acetylene in industry.
A metal organic framework compound, abbreviated as MOF, is a porous material having a periodic network structure formed by the interconnection of metal centers and organic ligands. Compared with traditional materials such as porous carbon, zeolite and the like, the MOF is characterized by designability of a structure, controllability of pore size and modifiability of a pore surface, so that the MOF has very important application prospects in a plurality of fields such as catalysis, storage, separation, drug delivery and the like.
In the synthesis of MOFs, the method of forming multi-core units by linking multiple metal ions to oxygen (O) centers has been widely proven to be one of the most effective strategies for constructing MOFs. At the same time, the MOFs thus prepared exhibit a specific function in the adsorptive separation of acetylene. However, polynuclear units formed by multiple metal ions and fluorine (F) centers are very rare in MOFs. Comparing the O atom with the F atom, it can be found that the F atom with larger electronegativity can form stronger hydrogen bond action with acetylene compared with the O atom, and is more beneficial to the adsorption of acetylene. Therefore, the synthesis of the MOF based on the multi-core unit formed by the metal ions and the F center and the application of the MOF in the adsorption and separation of acetylene have important significance for the development and application of novel MOF materials.
