Facile Synthesis of 20-nm-Thick ZIF-67 Films for Hydrogen Sieving Using β-Co(OH)2 Precursor Nanosheets
{{output}}
Zeolitic imidazolate framework-67 (ZIF-67) is an important class of nanoporous materials for high-performance membranes for gas separation, offering uniform-sized gas-selective pores. However, the fabrication of high-quality sub-100-nm-thick ZIF-67 membranes, ... ...
