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.
