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

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-...

Description
Summary: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. We investigate the role of the ionic liquid 1-methyl-3-octylimidazolium chloride as a crystallization additive in the hydrothermal synthesis of MIL-53(Al).
