“…Also, under the synergistic effect of the sharp edges of GO and the released Zn 2+ from the MOF, this type of composite could kill both Escherichia coli and Staphylococcus aureus efficiently. 211 Besides, many types of MOFs can be used to synthesize antibacterial hybrid materials with the GO pieces. For example, Wei and co-workers designed another composite based on GO and a Co-based MOF, which was also floriform.…”

“…Then, they use minimum inhibitory concentration (MIC) tests and disc diffusion for determining the antibacterial activity of the samples against Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 11,229 as the model strains of gram-positive and -negative bacteria. Finally, ZGO-1.0 (1 wt% of the GO-to-metal salt ratio) shows the greatest anti-bacterial activities, with the MIC values crucial for the inhibition of the bacterial growth of E [114].…”

Metal organic frameworks (MOF) are a class of hybrid networks of supramolecular solid materials comprising a large number of inorganic and organic linkers, all bound to metal ions in a well-organized fashion. Zeolitic imidazolate frameworks (ZIFs) are a sub-group of MOFs with imidazole as an organic linker to metals; it is rich in carbon, nitrogen, and transition metals. ZIFs combine the classical zeolite characteristics of thermal and chemical stability with pore-size tunability and the rich topological diversity of MOFs. Due to the energy crisis and the existence of organic solvents that lead to environmental hazards, considerable research efforts have been devoted to devising clean and sustainable synthesis routes for ZIFs to reduce the environmental impact of their preparation. Green chemistry is the key to sustainable development, as it will lead to new solutions to existing problems. Moreover, it will present opportunities for new processes and products and, at its heart, is scientific and technological innovation. The green chemistry approach seeks to redesign the materials that make up the basis of our society and our economy, including the materials that generate, store, and transport our energy, in ways that are benign for humans and the environment and that possess intrinsic sustainability. This study covers the principles of green chemistry as used in designing strategies for synthesizing greener, less toxic ZIFs the consume less energy to produce. First, the necessity of green methods in today’s society, their replacement of the usual non-green methods and their benefits are discussed; then, various methods for the green synthesis of ZIF compounds, such as hydrothermally, ionothermally, and by the electrospray technique, are considered. These methods use the least harmful and toxic substances, especially concerning organic solvents, and are also more economical. When a compound is synthesized by a green method, a question arises as to whether these compounds can replace the same compounds as synthesized by non-green methods. For example, is the thermal stability of these compounds (which is one of the most important features of ZIFs) preserved? Therefore, after studying the methods of identifying these compounds, in the last part, there is an in-depth discussion on the various applications of these green-synthesized compounds.
