Recent Progress in CO2 Capture by Porous Solid Materials

Climate change caused by global greenhouse gas emissions, especially CO2 emission, has become one of the most pressing environmental issues of our era. At present, carbon capture and storage have been considered as an effective strategy for mitigating the CO2 emission issue in the short term. Although the liquid amine-based CO2 capture system has been commercialized, some existing drawbacks, including large energy consumption for the regeneration process, equipment corrosion and solvent degradation, have motivated researchers to develop promising candidate materials for CO2 capture. Porous solid materials have been attracting much attention for CO2 capture in the last two decades due to their unique properties, including large surface area and pore volume as well as facile functionalization. In this paper, we summarized and discussed the latest progress (we focused on publications from the year 2017) in CO2 capture by porous solid materials, with a special emphasis on the effects of material porosities and surface functionalities on the corresponding CO2 capture performance. Future research prospects in this field were also pointed out and highlighted.
