Nanostructured sodium amide encapsulated in a porous silica gel matrix (“NaNH2-SG”) was investigated for CO2 capture and storage by in-situ gravimetric gas sorption. Exposure of NaNH2-SG to CO2 at 25 °C and 1 bar pressure resulted in ~3.6 wt% CO2 uptake over eight sorption/desorption cycles. Over 90...
