A Novel Zn-Cu Bimetallic Mixed-Component MOFs Composite for Efficient CO2 Capture

Year: 2025

Type: article

Abstract: In this work, a novel mixed-component bimetallic metal–organic framework (MOF) composite material was synthesized via a solvothermal approach, and its structural and textural properties were systematically characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), N2 adsorption/desorption analysis, and transmission electron microscopy (TEM). Furthermore, the single-component adsorption isotherms of CO2 and N2 were experimentally measured and fitted to the Langmuir–Freundlich model. The CO2/N2 selectivity of the composite was evaluated based on the ideal adsorption solution theory (IAST). The results demonstrated that the addition of Zn2+ significantly enhanced the specific surface area and improved the CO2 adsorption capacity (3.97 mmol/g at 35 °C and 1 bar), with an increase of 31.5% in comparison with the Cu-BTC/MCFs (3.02 mmol/g). Meanwhile, the Zn-Cu-BTC/MCFs had good recyclability and CO2/N2 selectivity up to 12.5 determined via IAST (CO2:N2 = 85:15).
