Title :

CO2 capture and conversion to fuels using magnesium nanoparticles under ambient conditions

Abstract :

Extensive use of fossil fuels is a major cause of anthropogenic CO2. Thus, CO2 capture and conversion are the keys in reducing its increased concentration in the earth's atmosphere.1 Many technologies were deployed to tackle the excess of CO2 present in the atmosphere.2,3 But the desired rate of CO2 conversion has not been yet achieved under ambient conditions. The harsh conditions of temperature and pressure make it less approachable. In this work, we have reported the use of magnesium (Mg) nanoparticles as well as bulk powder to capture and convert CO2 into valuable products under ambient conditions.4 It was observed that the Mg nanoparticles can also be deployed for the capture and conversion of CO2 from air. The mechanistic insights for CO2 conversion into methane, methanol and formic acid was studied by different techniques. This study demonstrates the first step towards sustainable CO2 utilization to produce fuel and chemicals.
