A sequential flow process of CO2 capture and conversion using cost-effective porous organic polymers†
Porous organic polymers (POPs) have shown significant potential for CO2 capture and utilization due to their high surface areas, tunable porosity, high stability, and ease of modification. Developing POPs for CO2 capture and catalytic conversion offers a viable solution to rising CO2 emissions. This study presents POPs composed of pyridine units, serving as dual functional materials that act as sorbents for CO2 capture and as substrates supporting silver chalcogenolate clusters (SCCs) for catalytic CO2 conversion. The scalable and cost-effective synthesis of these POPs enabled the design of pilot-scale breakthrough apparatus with two parallel POP sorbent beds for continuous CO2 capture from simulated flue gas, achieving a high working capacity of 20 Lflue gas kgPOP−1 h−1 for flue gas separation. Given the practical feasibility of using POPs for CO2 capture and the high catalytic activity of POPs loaded with SCCs in CO2 cycloaddition, a sequential process that integrates capturing CO2 from simulated flue gas and directly converting the captured CO2 into oxazolidinone achieves a high space–time yield of up to 9.6 g LPOP−1 day−1 in continuous operation. This study provides a viable strategy for CO2 capture and utilization using cost-effective, dual-functional porous materials.
期刊介绍:
Green Chemistry is a journal that provides a unique forum for the publication of innovative research on the development of alternative green and sustainable technologies. The scope of Green Chemistry is based on the definition proposed by Anastas and Warner (Green Chemistry: Theory and Practice, P T Anastas and J C Warner, Oxford University Press, Oxford, 1998), which defines green chemistry as the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Green Chemistry aims to reduce the environmental impact of the chemical enterprise by developing a technology base that is inherently non-toxic to living things and the environment. The journal welcomes submissions on all aspects of research relating to this endeavor and publishes original and significant cutting-edge research that is likely to be of wide general appeal. For a work to be published, it must present a significant advance in green chemistry, including a comparison with existing methods and a demonstration of advantages over those methods.
