Dense open metal sites in a microporous metal–organic framework for deep desulfurization with record‐high sulfur dioxide storage density

AIChE Journal (2022)

Zhenliang Zhu Ke Wu Xing Liu Peixin Zhang Shixia Chen

Abstract Dry desulfurization employing porous adsorbents is industrially preferred but efficient capture of sulfur dioxide (SO 2 ) at the ultralow concentration (i.e., 2000 ppm) is exceptionally challenging. Metal–organic frameworks with open metal sites (OMSs) can provide sufficient interactions with SO 2 , which, in turn, will degrade or compromise the structural robustness. Herein, we reported Cu‐ATC that contains dense oppositely positioned Cu OMSs for efficient trace SO 2 removal. Explicitly, Cu‐ATC adsorbs a benchmark amount of SO 2 (5.3 mmol g −1 ) at 0.01 bar with a record‐high SO 2 storage density of 2.23 g cm −3 at ambient conditions. The critical role of OMSs has been confirmed by the partially desolvated sample with declined uptakes and adsorption enthalpy. The desulfurization performances have been validated by multicycle breakthrough experiments even with mimic flue‐gas and water vapor. Computational simulations identify the adsorption sites at the molecular level. Combined with the high stability under various conditions, Cu‐ATC is a potent candidate for industrial implementation.

Fine pore engineering in a series of isoreticular metal-organic frameworks for efficient C2H2/CO2 separation

Nature Communications (2022)

Jun Wang Yan Zhang Yun Su Xing Liu Peixin Zhang

The separation of C2H2/CO2 is not only industrially important for acetylene purification but also scientifically challenging owing to their high similarities in physical properties and molecular sizes. Ultramicroporous metal-organic frameworks (MOFs) can exhibit a pore confinement effect to differentiate gas molecules of similar size. Herein, we report the fine-tuning of pore sizes in sub-nanometer scale on a series of isoreticular MOFs that can realize highly efficient C2H2/CO2 separation. The subtle structural differences lead to remarkable adsorption performances enhancement. Among four MOF analogs, by integrating appropriate pore size and specific binding sites, [Cu(dps)2(SiF6)] (SIFSIX-dps-Cu, SIFSIX = SiF62-, dps = 4.4'-dipyridylsulfide, also termed as NCU-100) exhibits the highest C2H2 uptake capacity and C2H2/CO2 selectivity. At room temperature, the pore space of SIFSIX-dps-Cu significantly inhibits CO2 molecules but takes up a large amount of C2H2 (4.57 mmol g-1), resulting in a high IAST selectivity of 1787 for C2H2/CO2 separation. The multiple host-guest interactions for C2H2 in both inter- and intralayer cavities are further revealed by dispersion-corrected density functional theory and grand canonical Monte Carlo simulations. Dynamic breakthrough experiments show a clean C2H2/CO2 separation with a high C2H2 working capacity of 2.48 mmol g-1.

Equilibrium and kinetic studies on adsorption of Pb(II) by activated palm kernel husk carbon

Desalination and Water Treatment (2015)

Zhengji Yi Jun Yao Hui-lun Chen Fei Wang Xing Liu

Batch experiments were conducted to study the ability of activated palm kernel husk carbon (APKHC) to adsorb Pb(II) ions from aqueous solutions. The effects of various operational parameters, such as temperature (25–55°C), pH (1.0–5.0), contact time (0–120 min), and adsorbent dose (0.5–3.5 g/L) were examined. The results suggested that the adsorption of Pb(II) is exothermic and strongly dependent on pH. The optimum pH for Pb(II) removal is 5.0. The Pb(II) uptake by APKHC was fast and reached an equilibrium in 80 min. The Pb(II) removal efficiency increased with increasing APKHC dosage up to 2.0 g/L, and then reached a plateau with approximately 97% of Pb(II) removed. Experimental data were fitted using Langmuir and Freundlich isotherms. The Pb(II) adsorption can be described well by the Langmuir model with a maximum monolayer uptake capacity of 98.04 mg/g. Kinetic study results suggested that the adsorption process proceeded according to the pseudo-second-order kinetic model. In short, APKHC can be used as an effective economical adsorbent for Pb(II) removal.
