We present a rapid temperature-assisted synthesis route to synthesize cyclodextrin-based metalorganic frameworks (CD-MOFs) surfactant freely in a short time. The cubic crystals of CD-MOF with an average edge length of 10-15 m, specific surface area 775 m 2 g -1 and total pore volume 0.229 cm 3 g -1 were synthesized in much shorter time rather than conventional CD-MOFs. To show the efficiency of the synthesized CF-MOF as adsorbent of gas, the uptake of CO2 at different temperature and pressure demonstrated. It is shown that the CO2 uptake increases with increasing pressure and decreasing temperature. Further microgravimetric investigation on gas adsorption at low pressures demonstrated superior gas uptake (147 mg g -1 c.a.) than previous reports. At the maximum equilibrium pressure, the uptake amounts of CO2 were found to be about the 326 and 268 mg g -1 at 303 and 323 K, respectively. The synthesized CD-MOF particles have great potential to be used in gas storage and separation applications.

“…The saturated adsorption capacity of UTSA-16 for hydrogen isotopes was 15.48 mmol/g, of which D 2 was 7.86 mmol/g and H 2 was 7.62 mmol/g. The hydrogen isotope adsorption capacity of UTSA-16 is lower than that of CAU-10-H, which is due to the lower specific surface area of UTSA-16 (581.5 m 2 / g) 48 than that of CAU-10-H (640 m 2 /g). 49 The uptake of D 2 by CAU-10-H is higher than those of some typical MOFs with open metal sites, such as Mg-MOF-74 (12.8 mmol/g), 34 CuBOTf (4.3 mmol/g), 26 and F-MOFCu (3.1 mmol/g).…”

H₂/D₂ Separation Using UTSA-16@CAU-10-H@γ-AlOOH Composites as the Stationary Phase in Gas Chromatography via the Additive Effects of Kinetic Sieving and Chemical Affinity Quantum Sieving

In this work, CAU-10-H@γ-AlOOH is prepared, and then UTSA-16 is loaded on CAU-10-H@γ-AlOOH to obtain UTSA-16@CAU-10-H@γ-AlOOH. Using the as-prepared composites as stationary materials by cryogenic gas chromatography at 77 K, while CAU-10-H@γ-AlOOH achieves the complete separation of ortho-H2 (o-H2) and D2 with a resolution R of 1.66 and a separation time t of 9.52 min, UTSA-16@CAU-10-H@γ-AlOOH achieves higher efficiency separation of hydrogen isotopes in a shorter separation time (4.56 min) with R = 1.7. Molecular simulation results show that CAU-10-H has both chemical affinity quantum sieving and kinetic sieving effects for H2/D2 at 77 K, and UTSA-16 can only exert the kinetic sieving effect. UTSA-16’s load on CAU-10-H@γ-AlOOH weakens the adsorption of hydrogen isotopes, and the presence of Co2+ in UTSA-16 promotes the conversion of para-H2 to ortho-H2. In gas chromatography, H2 was preferentially desorbed from the system due to strong D2 adsorption caused by the chemical affinity quantum sieving effect and faster H2 diffusion caused by the kinetic sieving effect. These additive effects achieved efficient hydrogen isotope separation at 77 K.

The separation of a Xe/Kr mixture is an industrially important but challenging process due to their inherent inert nature and similar atomic sizes. Porous materials containing open metal sites have been extensively proved to be an effective strategy for the Xe/Kr capture and separation. However, conventional materials with single open metal sites display the limitations of gas uptake at low pressure and separation selectivity of a Xe/Kr mixture. Herein M(pz)[Ni(CN) 4 ], simplify as MpzNi (M = Co, Ni, pz = pyrazine), with a suitable pore size and double accessible open metal sites, can synergistically afford strong interactions for Xe capture from a Xe/Kr mixture.CopzNi exhibits high uptake of 2.49 mmol/g at 20 kPa and a remarkable dynamic adsorption amount of Xe (2.35 mmol/g), outperforming most of previously reported materials. Density functional theory calculations further reveal that the excellent separation performance is driven by the compact pore size and cooperative interactions afforded by the double accessible open metal sites.
