Summary: In this report, we describe the synthesis of a zeolitic imidazolate framework (ZIF-8) using a simple mix and wait method. In a closed vial, the mixture of 2-methylimidazole and basic zinc carbonate spontaneously assembles into a crystalline product with approximately 90% conversion after 70 hours. The reaction exhibits sigmoidal kinetics due to the presence of self-generated water that accelerates the reaction.

Summary: ZIF-8 is synthesized by subjecting ZnO thin films deposited via plasma-enhanced atomic layer deposition to 2-methylimidazole vapor. The orientation of ZIF-8 crystals depends on the thickness and density of the precursor, with a more prominent orientation at longer conversion times. The thickness and roughness of ZIF-8 increase with conversion time.

Summary: MOF membranes have great potential in gas separation, but their industrialization is hindered by complex and time-consuming synthesis methods. This study successfully synthesized a series of ZIF-8 membranes using the fast current drive synthesis (FCDS) method on polydopamine-modified porous stainless steel hollow fiber substrates. The ZIF-8 hollow fiber membranes exhibited good selectivity and permeance, making significant progress in accelerating the industrialization of MOF membranes.

Summary: This study presents an effective strategy for the development of high-response volatile organic compounds (VOC) sensors by coating nano-metal oxides with metal-organic frameworks (MOF). The composite material, consisting of ZnO and ZIF-8, is able to form numerous pores and interface defects, enhancing the gas detection performance. The composite sensor exhibits optimal operating temperature at 350 degrees C and shows more than tripled response to 50 ppm gases compared to the ZnO sensor.

Summary: Bimetallic metal-organic frameworks (MOF) have gained attention for their synergic effect and enhanced properties compared to their parent structures. This study reports the synthesis of bimetallic Zn/Co-ZIF and its monometallic counterparts, ZIF-8 and ZIF-67, with a facile and low-cost method. Zn/Co-ZIF showed higher pore volume, BET surface area, and a slightly higher Zn-rich external surface.
