Metal-organic frameworks (MOF) could be define as porous crystalline materials that formed from the network synthesis of metal ions and clusters as nodes, and organic molecules as ligands. The flexibility in the components has led to the report of more than 20,000 different MOFs. MOF-5 could be mention as one of the most famous MOFs. These materials are divided into four categories of first, second, third, and fourth generation frameworks. There are various methods for the synthesis of MOFs, but the most common one is the thermal solvent method. Metal-organic frameworks sometimes perform better than other porous materials, such as activated carbon or zeolites. These materials have exceptional properties such as high surface area (6000 m2/g), porosity and high pore volume. The presence of these features along with high adjustability and flexibility has led to wide applications in various fields. Applications like gas storage and separation, catalytic applications, biomedical applications such as drug release, sensors, membranes and water purification. In the following study, the introduction of metal-organic frameworks, an overview of structural features and synthesis methods have been discussed, and then a number of common applications of these materials have been introduced and reviewed.
