“…[133] The material synthesis also follows the solvothermal reaction with Ln 2 O 3 , H 2 pydc, copper nitrate hexahydrate, and iodine molecules in water. [134] This MOF consists of binuclear [2Ni2S] nodes and pyrimidine-2-thiol as organic linkers. The UV irradiation is used in this work to activate HER.…”

society is still heavily relying on chemical fuels. Therefore, the essential and realistic approaches to environmental and energy issues remain to be the exploration of clean and sustainable energy sources, in order to meet the ever-increasing energy demand. Thanks to its high energy density and environmental friendliness, hydrogen fuel comes into play as a muchanticipated new energy carrier, which is under intensive studies in the academic field. [4] Furthermore, we are already in the new era witnessing the transformation of hydrogen-powered technologies from science fictions to realities. UK is already in the process of replacing their traditional diesel-powered double decker buses with the hydrogen-powered version, which aims to phase out the former by 2018. [5] China announced its world's first hydrogen-powered tram, which was put into business service in the latter half of 2017. [6] Mercedes-Benz had even started its development of personal hydrogen-powered car, and Toyota had commercialized its hydrogen fuel-cell car branded "Mirai." [7,8] However, one critical issue remains to be the conflict between the hydrogen production efficiency and the demand for the mass distribution of hydrogen-powered technologies.Current industrial hydrogen production methods include coal gasification (followed by water-gas shift reaction), steam reforming, cryogenic distillation, and water splitting. [9] Coal gasification and steam reforming utilize the reaction between conventional fossil fuels and water to produce syngas (primarily CO and H 2 ) or CO 2 and H 2 mixture. However, both reactions require high temperatures (can be over 1000 °C) and pressures, which is an energy intensive process and has strict requirements on infrastructures. [10] The reaction products also need to be further separated to obtain relatively high-concentration of hydrogen. Cryogenic distillation takes the advantage of difference in gas boiling points, which can be applied to separate hydrogen from other gas components in the former two hydrogen production methods. However, cryogenic distillation is also an energy intensive process for low-temperature gas liquification. In comparison, hydrogen evolution reaction (HER) through water splitting is much-favored because of the following three prominent advantages: 1) Water splitting can be carried out at room temperature and ambient pressure, which is less restricted by infrastructure requirements. 2) Oxygen and hydrogen can be produced separately or selectively, which eliminate the need for gas separation. 3) Both the hydrogen source Highly efficient hydrogen evolution reactions (HERs) will determine the mass distributions of hydrogen-powered clean technologies in the future. Metal-organic frameworks (MOFs) are emerging as a class of crystalline porous materials. Along with their derivatives, MOFs have recently been under intense study for their applications in various hydrogen production techniques. MOF-based materials possess unique advantages, such as high specific surface area, crystalline porous str...

“…Both the Fe-centres are connected to terminal CO and CN ligands with one of them bound to a Fe 4 S 4 ferredoxin cluster via a cystinyl residue. 182 In order to employ this photochemical system in the MOF skeleton, two strategies have been adopted: either photo-catalytically active MOFs in conjunction with proton reducing agents or MOFs featuring proton reducing groups as linkers and an external photosensitizer are employed to produce H 2 from water. Two other Cys (Cys-543 and Cys-72) bind the Ni atom terminally to complete its tetrahedral coordination sphere.…”

In this review, we have portrayed the structure, synthesis and applications of a variety of biomimetic MOFs from an unprecedented angle. Synthetic MOF analogues of five distinct enzymes: phosphotriesterase, hydrogenase, cytochrome P450, chymotrypsin and carbonic anhydrase, have been discussed with their skeletal comparison to actual enzymatic active sites as reference, and an explanation of catalytic pathways from the mechanistic cycle of the corresponding enzymes is depicted. We demonstrated critically each of the five discrete situations by assimilating available benchmark researches in an attempt to provide a concise literature source on the ingenious design strategies and versatile biomimetic applications of this domain of materials.

“…Among the strong bonds one finds the classic M-OR and M-O 2 CR links, and a very large number of MOFs are also built upon M-N coordination bonds. Concurrently, the M-SR linkages where RS -is a thiolate have been employed in a somewhat less extent, but can clearly lead to MOFs and 3D coordination polymers, including copper as the metal (about 25 structures) [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Conversely, the weaker dative Cu(I):SRR' bond, where RSR' is either a cyclic or acyclic mono-or di-or polythioether have attracted less attention [28][29][30][31].…”

This mini-review surveys 23 structures of 3D coordination polymers built upon mono-, di-as well as cyclic and acylic polythioethers. An emphasis is put on the Secondary Building Units (SBU) and the physical properties. Importantly, the key feature is that the dominant SBU is not the rhomboid (Cu 2 X 2 S 4 ), but an inorganic polymer containing at least the chain of the type (CuX) n . In the latter type of SBU, these chain formations are observed for X = I, but predominantly for X = CN. In addition, a large portion of the surveyed materials exhibit rich photophysical properties, but on several occasions, these materials exhibit properties often attributed to MOFs, mainly solvent exchange.
