In recent years, environmental pollution has been identified as a matter of concern owing to its exponential growth. The rapid growth of human population and increased anthropogenic activities are releasing enormous amounts of carbon dioxide and other greenhouse gases into the environment and influencing the global climate and earth’s temperature. Therefore, the development of efficient and low-cost technologies to capture CO and other greenhouse gases are in great need to render a clean environment. To address the issue of environmental pollution, the scientific community is specially engaged in developing efficient and low-cost gas sequestration technologies. Among the existing technologies, adsorption of pollutant gases onto porous sorbents is contemplated as the most cost-effective and efficient approach. Over the years, a broad range of nanocomposite materials have provided promising results for gas separation applications owing to their improved properties compared to their pure equivalents. As a result, scientists have developed numerous advanced nanocomposite materials and evaluated their gas sorption capacity in recent years. This review discusses the most recent nanocomposite materials successfully explored for gas separation applications. Besides this, the advanced synthesis methods of nanocomposites and their physiochemical characteristics are discussed in detail. Additionally, the reaction mechanism for the adsorption of toxic gases using nanocomposites, optimization parameters, kinetics and selectivity studies, followed by the techno-economics of nanocomposites are comprehensively discussed. Overall, this review bestows futuristic information on advanced nanocomposites developed for gas separation applications, followed by concluding remarks.
