Abstract

The atmospheric carbon dioxide levels are steadily increasing which requires urgent action for its capture, storage, and utilization. To mitigate CO2 effectively and economically research has been focused to improving CO2 capture and storage technologies. Conventional technologies possess a number of shortcomings including space limitations, high energy consumption, high cost as well as solvent handling problems. The ability of solid sorbents and membranes in CO2 separation provoked researchers to develop advanced sorbents and membranes mainly composed of polymers. In this preview important role of radiation technology in developing such materials has been discussed with special emphasis on the use of metal-organic frameworks as the state-of-the-art fillers in the preparation of mixed matrix membranes (MMMs) for capturing CO2. The use of ionizing radiation in converting CO2 into useful value-added products is explored in terms of radiation-induced modification of catalysts used in thermal, electro- and photo-induced reduction of CO2. Successful examples of radiation chemistry applied to the development of materials and processes in mitigating carbon footprint are discussed with a future outlook.
