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.

“…Constructing from imidazolate linkers and metal ions, ZIFs are considered as a rising star in different photocatalytic applications. Indeed, it is demonstrated that the inherent and specific properties of ZIFs can significantly boost the photocatalytic performance of CO 2 reduction. − For example, Meng et al studied the photoreduction of CO 2 using ZIF-67 coupled with graphitic carbon nitride (g-C 3 N 4 ) under solar-light irradiation and obtained ∼50 μmol h –1 of ethanol with high stability and selectivity. Wu et al studied the separation of CO 2 using ZIF-67 (Co as metal ions) embedded with polymers and obtained higher selectivity toward CO 2 separation compared with ZIF-8 (Zn metal ions).…”

Nowadays, charge separation and efficient solar-light absorption are the main challenges in the photoreduction of CO 2 . Although significant efforts have been made to overcome these issues, including the use of cocatalysts and doping, photocatalysts still suffer from low photocatalytic activity and stability. Herein, the localized surface plasmonic resonance (LSPR) effect of Au nanoparticles deposited into the zeolitic imidazolate framework (ZIF-67) was investigated for the photoreduction of CO 2 . Different Au loadings in ZIF were prepared and their effects were studied on photocatalytic performance. Plasmonic Au nanoparticles (PNPs) in the size range of 30−40 nm improved visible-light absorption, enhanced charge separation, and played an important role in selectivity. A volcano relationship of plasmonic Au NPs with methanol and ethanol generation was found, along with the deposition of plasmonic Au nanoparticles. A total yield of 2.5 mmol g −1 h −1 of methanol and 0.5 mmol g −1 h −1 of ethanol were obtained, which are the highest values compared to those reported in other studies. Finally, our results revealed that Au PNPs have a significant impact on the selectivity and photocatalytic activity of ZIF-67 for the photoreduction of CO 2 and could be a promising alternative toward designing plasmonic reticular materials.
