Abstract

AbstractDeveloping advanced porous materials possessing both a high storage capacity and selectivity for acetylene (C2H2) remains challenging but a sought-after endeavor. Herein we show a strategy involving synergic combination of spatial confinement and commensurate stacking for enhanced C2H2storage and capture via maximizing the host—guest and guest—guest interactions. Two ultramicroporous metal-organic frameworks (MOFs), MIL-160 and MOF-303 are elaborately constructed to exhibit ultrahigh C2H2uptakes of 235 and 195 cm3·g−1, respectively, due to the confinement effect of the suitable pore sizes and periodically dispersed molecular recognition sites. Specially, C2H2capacity of MIL-160 sets a new benchmark for C2H2storage. The exceptional separation performances of two materials for C2H2over both CO2and ethylene (C2H4), which is rarely observed, outperform most of the benchmark materials for C2H2capture. We scrutinized the origins of ultrahigh C2H2loading in the confined channels via theoretical investigations. The superior separation efficiency for C2H2/CO2and C2H2/C2H4mixtures with unprecedented C2H2trapping capacity (> 200 L·kg−1) was further demonstrated by dynamic breakthrough experiments.
