Summary:With the current high consumption of fossil fuels and the rapid increase in atmospheric CO 2 concentrations, there is a strong need for energy efficient and selective capture of CO 2 from fossil-fuelled power plants and other large industrial sources. Among the various adsorbents explored by the scientific community for CO 2 removal from flue gases, graphene is receiving increased attention because of its unique molecular structure and many exciting properties such as high mechanical strength, excellent thermal conductivity, good chemical stability, large accessible surface area, and tunable porosity. In addition, the facile surface functionalization of graphene leads to production of innovative graphene-based materials that have the potential to be applied as advanced next-generation CO 2 adsorbents. As a consequence, graphene and its derivatives have been the subject of intense experimental investigations and theoretical studies in recent years, probing their unmatched structural versatility for CO 2 abatement. This review aims at bringing together the latest developments in the rapidly evolving cross-disciplinary field of graphene-mediated CO 2 adsorption and it provides new research directions for making further advances toward practical deployment of graphene-based CO 2 adsorbents. A review of recent advances in graphene-mediated CO 2 adsorption from flue gases, a rapidly evolving cross-disciplinary field of current global interest.
