In a study published in Nature Communications, a research team led by Prof. YANG Weishen and Assoc. Prof. PENG Yuan from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences developed a wear-resistant MOF membrane, ZIF-67, featuring a tangential-normal interweaving configuration. This membrane enables accurate separation of propylene from propane by utilizing the paralyzed cage windows and addressing intergranular defects.
