Hybrid ultramicroporous materials (HUMs) with enhanced stability and trace carbon capture performance†
Abstract
Fine-tuning of HUMs through pillar substitution can significantly enhance trace CO2 sorption performance and stability. The resulting materials, exemplified by the new material TIFSIX-3-Ni, [Ni(pyrazine)2(TiF6)]n, are shown through temperature programmed desorption experiments to remove trace quantities of CO2 from moist gas mixtures.
