Among the various materials investigated for CO2 capture, functionalized graphene has shown considerable promise due to its remarkable characteristics, such as a high surface area, robust mechanical properties, and adjustable chemical functionalities. This review article offers a thorough examination of the latest developments in the use of functionalized graphene for CO2 capture, focusing on its improved adsorption capacity, selectivity, and reusability. We explore innovative methods of functionalization, the combination of functionalized graphene with advanced materials like metal-organic frameworks (MOFs) and zeolites, and the critical role of environmental and economic sustainability in the advancement of these materials. Additionally, we stress the importance of real-world applications and pilot studies to evaluate the practical feasibility of functionalized graphene in industrial contexts. By consolidating current research and outlining future pathways, this paper seeks to aid ongoing initiatives aimed at combating climate change through effective CO2 capture methods, ultimately facilitating the shift towards a sustainable low-carbon economy. Research Highlights In this review the application of functionalized graphene for CO2 capture was reviewed. Functionalized graphene presents a highly effective solution for CO2 The application of nanotechnology in carbon capture is still in the experimental phase. To enhance the performance of functionalized graphene for CO2 capture, advancements in functionalization methods are essential.
