The ability to produce high-grade fuels and chemicals by reutilizing CO2 is becoming indisputably realizable thanks to the development of knowledge of certain mechanisms and progress in theability to use existing technologies. The current atmospheric concentration of CO2, its environmental impacts, and the increasing levels of human activity stimulate the development of reliable and affordable renewable clean fuel technologies, based on CO2 conversion for achieving the closing of the carbon cycle. Meeting this goal is of great importance , but doing so is full of challenges in relation to prospects for global application. The fundamentals of thermo-catalvtic conversion of CO2 and the key materials andsystems needed have led to considerable research attention in the context of creating clean industrial feedstock, a greener economy, and a protected environment. This article investigates recent progress in CO2 thermo-catalytic conversion mechanisms. The combination of CO2 feed with other reactive gases, such as H2O, CH4, and renewable H2 could be able to achieve high levels of CO2 re-use , thanks to the higher conversion kinetics and much more thermodynamic favorability at milder operating conditions.
