Materials, Vol. 11, Pages 183: Effective Capture of Carbon Dioxide Using Hydrated Sodium Carbonate Powders Materials doi: 10.3390/ma11020183 Authors: Yuanhao Cai Weilin Wang Liang Li Zhaofeng Wang Suying Wang Hao Ding Zhengguo Zhang Luyi Sun Weixing Wang The emission of CO2 has been considered a major cause of greenhouse effects and global warming. The current CO2 capture approaches have their own advantages and weaknesses. We found that free-flowing hydrated sodium carbonate (Na2CO3) powders with 30 wt % water can achieve a very high CO2 sorption capacity of 282 mg/g within 60 min and fast CO2 uptake (90% saturation uptake within 16 min). The results suggest that the alkaline solution resulting from the dissolution of partial Na2CO3 can freely attach onto the hydrated Na2CO3 particles, which provides an excellent gas–liquid interface for CO2 capture, leading to significantly enhanced CO2 sorption capacity and kinetics.
