Control of interpenetration in a microporous metal–organic framework for significantly enhanced C2H2/CO2 separation at room temperature†
Abstract
A novel non-interpenetrated three-dimensional porous metal–organic framework UTSA-68 has been controllably synthesized by altering the reaction conditions. The resulting UTSA-68a shows a notably higher porosity and adsorption selectivity (3.5–5) for C2H2/CO2 separation compared to that of doubly interpenetrated ZJU-30a (1.7–2.4) at room temperature.
