Phyllosilicate nanoclay-based aqueous nanoparticle sorbent for CO2 capture at ambient conditions. (December 2017) - Fu, Liling
Graphical abstract: Highlights: A new and effective aqueous nanoparticle sorbent for CO2 capture is developed based on aminoclay. Carbon capture of the aminoclay sorbent combines the advantages of both liquid and solid amine sorbents. The aminoclay sorbent exhibits high CO2 recuperation capacity at ambient conditions and reduced sorbent loss due to volatility. Abstract: We report a new and effective aqueous sorbent for CO2 capture at ambient conditions based on aminopropyl magnesium phyllosilicate nanoparticles (aminoclay). Combining the advantages of both liquid and solid amine sorbents, the aminoclay sorbent is easy to synthesize, and exhibits CO2 recuperation capacity of ∼4 mmol/g at steady state and reduced sorbent loss due to volatility making it a promising candidate for carbon capture technologies.
