Abstract
Electrochemical deposition has emerged as a novel approach to fabricate metal–organic framework (MOF) films. Here, for the first time, an aqueously cathodic deposition (ACD) approach is developed to fabricate ZIF-8 type of MOF membranes without addition of any supporting electrolyte or modu-lator. The fabrication process uses 100% water as the sole solvent and a low-defect density membrane is obtained in only 60 min under room tem-perature without any pre-synthesis treatment. The membrane exhibits supe-rior performance in C3H6/C3H8 separation with 182 GPU C3H6 permeance and 142 selectivity, making it sit at the upper bound of permeance versus selectivity graph, outperforming majority of the published data up to 2019. Notably, this approach uses an extremely low current density (0.13 mA cm−2) operated under an ultrafacile apparatus set-up, enabling an attractive way for environmentally friendly, energy efficient, and easily scalable MOF membrane fabrications. This work demonstrates a great potential of aqueously electro-chemical deposition of MOF membrane in the future research.Citation
