“…After that, it is left to stand for several hours, and then, ZIF-8 crystals are separated by centrifugation from the milky emulsion, washed with methanol, and dried in air for further use. Considering the potential application of ZIF-8 materials, various methods of preparing ZIF-8 have been developed, including traditional methods such as solvothermal, 69 hydrothermal, mechanical, 69−71 sonochemical, 72,73 microwave-assisted 69 methods, and some other industrial methods such as solvo-jet, 74,75 T-mixer, 6 and electrochemical techniques. 76 Though 10 years have passed since the first ZIF-8 was synthesized by Park and co-workers, 38 as far as we know, there have been only a few systematic reviews focusing on the synthetic factors, which would affect the outcome of ZIF-8 production in general.…”

Zeolite imidazolate frameworks (ZIFs), as an important part of metal−organic frameworks (MOFs), have received great attention in many application fields, such as gas adsorption, separation, and catalysis. It was found that the performances of these applications largely depend on ZIFs' properties, such as particle size distribution, pore size, and specific surface area, which are essentially controlled by different synthetic methods. Among all the disclosed ZIF-type structures, researches on ZIF-8 are growing since it has high chemical and thermal stability and a flexible structure. Therefore, ZIF-8 was chosen as an example in this review to illustrate how synthetic factors affect the final properties of ZIF materials. We summarize the evolution process of ZIF-8 which is divided into three stages: supersaturation, nucleation, and particles. Emphasis is placed on the discussion of the influences of various factors on the formation of ZIF-8. The factors are classified into several types such as various salt sources, concentration of reactants, solvents, temperature, and so on. The challenges, prospects, and outlook of ZIF-8 in the future are presented last. This perspective aims to provide necessary information for industrial synthesis of MOF and other porous materials in the future.

“…However, several protocols have been published on the generation of MOFs in the water phase. In this case, the strategy includes the application of the proper excess of the organic linkers and appropriately set pH to provide successful coordination to the metal cations [27][28][29].…”

In the past decade, much effort has been devoted to using chemical clock-type reactions in material design and driving the self-assembly of various building blocks. Urea-urease enzymatic reaction has chemical pH clock behavior in an unbuffered medium, in which the induction time and the final pH can be programmed by the concentrations of the reagents. The urea-urease reaction can offer a new alternative in material synthesis, where the pH and its course in time are crucial factors in the synthesis. However, before using it in any synthesis method, it is important to investigate the possible effects of the reagents on the enzymatic reaction. Here we investigate the effect of the reagents of the zeolite imidazole framework-8 (zinc ions and 2-methylimidazole) on the urea-urease reaction. We have chosen the zeolite imidazole framework-8 because its formation serves as a model reaction for the formation of other metal–organic frameworks. We found that, besides the inhibition effect of the zinc ions which is well-known in the literature, 2-methylimidazole inhibits the enzymatic reaction as well. In addition to the observed inhibition effect, we report the formation of a hybrid urease-zinc-2-methylimidazole hybrid material. To support the inhibition effect, we developed a kinetic model which reproduced qualitatively the experimentally observed kinetic curves.
