Production of Organometallic Frameworks in Least Possible Time
Tehran, Iran | Posted on September 23rd, 2014 The time required for the production of nanostructures significantly decreases by using this method. Results of the research will have applications in gas and petrochemical industries.
Organometallic frameworks are classified as a new generation of porous crystalline materials. Size reduction of the particles to nanometric scale is very fantastic. Modulation is one of the methods used for the production of these compounds at nanometric scale. In this method, a functional group similar to one of the organic cross-linkers is used. In competition with organic cross-linkers, the functional groups surround the metallic active site and prevent the organometallic framework from growing towards that direction.
Taking into account the results of the research, organometallic frameworks can be produced at nanometric scale in the least possible time by combining the two methods of modulation and sonochemical.
Dr. Seyed Mohammad Amin Alavi explained about the results of the research, and said, "We succeeded in the production of organometallic nanorods in less than 90 minutes by combining modulation and sonochemical methods. In case modulation method is used solely, it has been reported that the production of these nanorods required at least 24 hours. Moreover, the size of obtained structures would be higher than 100 nm if sonochemical method is used solely. By combining this method with modulation method, nanorods at 80 nm scale were produced successfully."
This type of compounds is used as sorbents, gas storages, and catalysts due to their high porosity. Therefore, they can be used in gas and petrochemical industries and even as drug carrier for medical purposes.
Results of the research have been published in Ultrasonics Sonochemistry, vol. 22, issue 1, 2015, pp. 349-358.
