Abstract
The excessive CO
2
emissions in the atmosphere and the consequent climate change have motivated the interest in studying CO
2
utilization processes. Among these CO
2
upgrading reactions, reverse water gas shift (rWGS), CO
2
methanation, and dry reforming of methane (DRM) have been studied widely because the concentration of CO
2
in air could be reduced by running the above reactions and their products can be used as fuel. However, the large‐scale industrial application for these CO
2
utilization processes has been hindered by the side reactions and the vast input of heat. Therefore, developing highly active, selective, and s
catalysts is of importance. This chapter aims to provide a comprehensive overview of recent advances on catalysts toward the above three CO
2
utilization processes; synthesis methods, catalytic performances, and limitations of different catalysts have been carefully analyzed. In addition, the backgrounds and fundamentals of these reactions are also critically reviewed.
