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.
