Effects of Particle Size on the Gas Uptake Kinetics and Physical Properties of Type III Porous Liquids.

ABSTRACT: Type III porous liquids (PLs) consist of porous solid particles dispersed in a size-excluded liquid phase and are attracting much attention as novel media for applications such as gas separation. However, the effects of fundamental variables such as particle size on their physical properties are currently largely unknown. Here we study the effects of particle size in a series of porous liquids based on solid Al(OH)(fumarate) (a microporous metal-organic framework, MOF) with particle sizes of 60 nm, 200-600 nm, or 800-1000 dispersed in liquid polydimethylsiloxane (PDMS). Properties examined include physical stability of the dispersion, viscosity, total CO₂ uptake, and kinetics of CO₂ uptake. As expected, both physical stability and viscosity decreased with increasing p
