Zeolitic Imidazolate Framework‐8 (ZIF‐8) membrane is well recognized for its great capability in efficient C3H6/C3H8 separation, and their sustainable fabrication is extremely advantageous for batch production and commercial application. In this study, a solvent‐free protocol was developed for sustainable production of ZIF‐8 membranes with exceptional C3H6/C3H8 selectivity through combining atomic...
Continuous Covalent Organic Frameworks Membranes
Advanced covalent organic frameworks (COFs) membranes have received a lot of attention and a better trade‐off between selectivity and permeability can be achieved due to the tunable pore size, high porosity, unique pore structure and the abundance of molecular/ion‐specific functional groups on the framework. In article number 2303757, Li Gao, Xiaoming...
Covalent organic frameworks (COFs) are porous crystalline polymeric materials formed by the covalent bonding of organic units. The abundant organic units library gives the COFs species diversity, easily tuned pore channels, and pore sizes. In addition, the periodic arrangement of organic units endows COFs regular and highly connected pore channels, which has led to the rapid development of COFs in...
Single‐Atom Catalysts
An integrated structure of core‐shell carbon nanoboxes doped with single Fe atoms wrapped with self‐growing carbon nanotubes is designed to modify the polypropylene (PP) membrane (Fe@C‐CNT). Self‐growing carbon nanotubes and carbon nanowires can significantly shorten the electron transfer distance and improve the conductivity of the catalyst. In addition, this unique rational...
Herein, an integrated structure of single Fe atom doped core‐shell carbon nanoboxes wrapped by self‐growing carbon nanotubes (CNTs) is designed. Within the nanoboxes, the single Fe atom doped hollow cores are bonded to the shells via the carbon needles, which act as the highways for the electron transport between cores and shells. Moreover, the single Fe atom doped nanobox shells is further wrapped...
