Abstract
Carbon dioxide (CO2) is a significant greenhouse gas that has been identified as a major contributor to global warming and climate change. Carbon dioxide is a non-toxic and readily accessible gas that may be used to make a variety of products, including cyclic carbonates, carbamates, urethanes, substituted ureas, organic carbonates, methanol, and hydrocarbons. One such key transition is the cycloaddition of CO2 and ethanolamine to produce cyclic carbamate. The primary objective of this work is to develop a catalyst that is both stable and active and has high selectivity for the direct synthesis of 2-oxazolidinone from CO2 and ethanolamine. The Zn/CeO2 nanorod exhibits a higher number of oxygen vacancies in comparison to the cubic and nanorod shapes of CeO2. These oxygen vacancies may stabilize the CO2 molecule by filling one of its oxygen atoms, hence improving catalytic efficacy. Zn/CeO2 nanorods catalyst show significantly more activity for 2-oxazolidinone synthesis from CO2 and ethanolamine, as Zn improves CeO2 surface reducibility. We extensively characterized catalysts to understand their physicochemical properties and correlation with catalytic activity. Under optimum reaction condition 93.7% of ethanolamine conversion and 97.8% selectivity for 2-oxazolidinone were achieved.
