Rising carbon dioxide (CO2) levels in the atmosphere from anthropogenic sources have led to the development of carbon capture, utilisation and storage (CCUS) technologies. In order to decarbonise chemical synthesis, a process intensification approach can be employed, wherein CO2 capture is coupled to a chemical reaction in a way that improves energy efficiency and product yields. In this review paper, we present advances in CO2 adsorbent development for process intensification, focusing on applications that have achieved a synergistic effect between CO2 adsorption and catalytic reactions that either consume or generate CO2. Firstly, we present a range of solid CO2 adsorbents of varying capability to capture CO2. Then we present a short introduction to the importance of developing CO2 adsorbents for process intensification. In order to improve the direction of research in the future, we emphasise the importance of developing compatible adsorbents and catalysts that operate synergistically and discuss the importance of cross cutting themes in process intensification and research opportunities for the future.
