ABSTRACT

CO2 is thermodynamically and kinetically stable, making its conversions to other chemicals and fuels difficult. However, CO2 can be attacked by nucleophiles, and electron-donating reagents ascribe to the electron deficiency of carbonyl carbons. Therefore, the conversion of CO2 is achievable in practice despite technological barriers. Key aspects such as molecular structure, thermodynamics, and kinetics of CO2 are introduced in Chapter 2. In thermodynamics, CO2 conversion processes are endothermic under a standard state, which shows the CO2 conversion reactions are non-spontaneous. In addition, CO2 conversion is difficult from a kinetics standpoint. Particularly, poor catalytic activity and/or insufficient stability of catalysts are the largest challenges in CO2 conversions.
