Phyllosilicate nanoclay-based aqueous nanoparticle sorbent for CO2 capture at ambient conditions

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. 1 2017 Elsevier Ltd
