New catalysts and methods to utilize CO2

My research is based on CO2 adsorption and utilisation…. An obvious question of what do we do with CO2!!! We don’t fill up the cylinders to store it.  But we develop new catalysts and methods to utilize CO2 in terms of fine chemicals.

The continued use of fossil fuels is anticipated for many years to come, owing to the slow rate of transition toward renewable and clean energy sources. Very recent reports have shown the concentration of the central greenhouse pollutant carbon dioxide (CO2) has already surpassed the permissible level and continues to accumulate more in the atmosphere at an alarming rate. Even in May, very high temperature to 480C was a note. Unfortunately, India stood among the top 10 hottest places out of 15 places in the world. (Weblink). So, CO2 capture and its fixation in terms of chemical conversion are the areas of presently concentrated interest.

On the other hand, the nontoxicity and simple, attainable quality of anthropogenic CO2 open up its potential as a substantial C1 source in the assembling of a few esteem included compounds. In specific, the valorization of CO2 with epoxides to yield cyclic carbonate is a 100% particle monetary and appealing strategy. The development of new pre-functionalised material for task-specific applications is the current area of interest and curiosity of new materials have opened up fields of new synthetic material for various application. Metal-Organic Frameworks, widely known as MOFs, is one of the emerging research interest. These multipurpose materials are employed as the catalyst, sensors, adsorbents, and for separation purpose. One of the presents filed of MOFs is the fixation of CO2 in terms of cyclic carbonate at ambient temperature and pressure. So far, people have done research using very harsh conditions(High temperature and high pressure). These MOF materials provide a very high Brunauer–Emmett–Teller (BET) surface area and thus act as adsorbent and simultaneously convert these to cyclic carbonates. Pores of The structural advantages of MOF such as tailorable compositions, pore volume pore size, morphologies, and functionalities trigger the catalytic properties of MOF. In conclusion, functionalized frameworks can open up a new era in the field of CO2 utilization approaching towards a greener way to reduce greenhouse gases.
