CO2 adsorption by carbonaceous materials and nanomaterials

Abstract Policy changes in anthropogenic CO2 reduction are increasingly looking at the simultaneous development of attractive technologies that integrate its industrial utilization in valorizing the captured CO2 to fuel. Carbonaceous nanoadsorbents are attractive regenerative materials allowing for derivation from waste precursors, which makes them cost-effective and efficient for the given purpose. This chapter aims to review solid carbon-based nanoadsorbents for use in carbon dioxide capture traversing through their sources, chemistries, and mechanisms of adsorption and including structural developments aimed at carbon dioxide capture. As a conclusion, it is deemed that the future outlook will veer toward structures with industrial production and engineering feasibility, especially those that entail both precursors with waste valorization and integration with clean energy technologies such as solar for conversion of captured waste CO2 to fuel.
