A Zr-based metal-organic framework (MOF-801) with high thermal and chemical stability was prepared by the solvothermal synthesis method. Notably, MOF-801 exhibits a high separation selectivity for CH/CH and CH/CH, making it a practical material for the storage and purification of light alkanes.

With the organosilica nanocompartments inside the r-GO stacks and the intensified polymerization, r-GO sheets endow the as-prepared hybrid membranes with high H and CO separation performance. The resulting selectivities of H/CH and CO/CH are found to be 223 and 55, respectively, together with gas permeance of approximately 2.

MIL-96 crystals with dodecahedral and hexagonal column shapes were successfully synthesized by tuning the OH(-) ion content of the synthesis solution. When the OH(-) ion content was further increased, MIL-110 with a nanorod morphology appeared as the product.

Although the surface area and pore volume of MIL-101 decreased significantly after loading PEI, all the resulting composites exhibited dramatically enhanced CO2 adsorption capacity at low pressures. At 100 wt% PEI loading, the CO2 adsorption capacity at 0.

The intercrystalline defects of the ZIF-90 membrane are minimized to enhance the separation selectivity while a high permeance is maintained.
