Abstract

Abstract : Both high SO2 uptake and excellent SO2 /CO2 selectivity are achieved by an organic cage-based hydrogen-bonded organic framework (HOF) material based on experimental and theoretical studies. Abstract : A cucurbit[6]uril cage-based hydrogen-bonded organic framework (HOF) shows high capacity of SO2 capture (up to 4.98 mmol g −1 at 1 bar and 293 K), high SO2 /CO2 selectivity, good chemical stability toward dry SO2, and outstanding cycling performance. The preferential adsorption sites on the cage of the HOF are revealed by DFT calculations and FT-IR.
