Influence of 1-methyl-3-octylimidazolium chloride on MIL-53(Al) crystallinity and particle size

Abstract

Little is known about ionic liquids as MOF crystallization additives. We investigate the role of 1-methyl-3-octylimidazolium chloride (OmimCl) in MIL-53(Al) hydrothermal synthesis. Higher crystallinities and particle sizes with 0.05–0.50% v/v OmimCl suggest preferential growth along [001]. With 1.0–10% v/v OmimCl, missing linkers and lower crystallinities indicate arrested growth.
