J Nanosci Nanotechnol. 2019 Jun 1;19(6):3059-3078. doi: 10.1166/jnn.2019.16647.

Abstract

The carbon dioxide (CO₂) is notorious as the greenhouse gas, which could cause the global warming and climate change. Therefore, the reduction of the atmospheric CO₂ emissions from power plants and other industrial facilities has become as an increasingly urgent concern. In the recent years, CO₂ capture and storage technologies have received a worldwide attention. Adsorption is considered as one of the efficient options for CO₂ capture because of its cost advantage, low energy requirement and extensive applicability over a relatively wide range of temperature and pressure. The metal organic frameworks (MOFs) show widely potential application prospects in CO₂ capture and storage owing to their outstanding textural properties, such as the extraordinarily high specific surface area, tunable pore size, ultrahigh porosity (up to 90%), high crystallinity, adjustable internal surface properties, and controllable structure. Herein, the most important research progress of MOFs materials on the CO₂ capture and storage in recent years has been comprehensively reviewed. The extraordinary characteristics and CO₂ capture performance of Zeolitic Imidazolate Frameworks (ZIFs), Bio-metal organic frameworks (bio-MOFs), IL@MOFs and MOF-composite materials were highlighted. The promising strategies for improving the CO₂ adsorption properties of MOFs materials, especially the low-pressure adsorption performance under actual flue gas conditions, are also carefully summarized. Besides, CO₂ is considered as an abundant, nontoxic, nonflammable, and renewable C1 resource for the synthesis of useful chemicals and fuels. The potential routes for resource utilization of the captured CO₂ are briefly proposed.
