RESUMEN
The toluene adsorption properties of InOF-1 are studied along with the confinement of small amounts of this non-polar molecule revealing a 1.38-fold increase in CO2 capture, from 5.26 wt% under anhydrous conditions to 7.28 wt% with a 1.5 wt% of pre-confined toluene at 298 K. The InOF-1 affinity towards toluene was experimentally quantified by ΔH ads (-46.81 kJ mol-1). InOF-1 is shown to be a promising material for CO2 capture under industrial conditions. Computational calculations (DFT and QTAIM) and DRIFTs in situ experiments provided a possible explanation for the experimental CO2 capture enhancement by showing how the toluene molecule is confined within InOF-1, which constructed a "bottleneck effect".
