“…Several Cu based nanostructured oxides and model complexes have been reported as catalysts ,including electro-catalysts and photo-catalysts . [10][11][12][13][14] Both CuO and Cu2O are inherently p-type and have shown promise as photocathodes for water splitting due to their suitable position of conduction band edges with respect to the potential for H2O/H2.

“…Previous reports have shown that the conduction band potential (E CB ) of n-type semiconductors was approximately 0.1 or 0.2 eV less than its E fb . 42 Relative to SCE, the conduction band positions of MCS and Co 9 S 8 were approximately −1.41 and −1.03 eV. It is calculated according to the formula E NHE = E SCE + 0.24 eV.…”

“…40,41 Due to its unique morphology and structure, the metal-organic framework (MOF) provided spatial support for the catalysts that were prone to agglomeration so that it can be uniformly dispersed, improve light-trapping capacity and expose more active sites. For example, Cu 3 P 42 and Co 3 O 4 43 synthesized with MOF as a template. A suitable template can successfully construct a hollow structure catalyst.…”

The photocatalytic hydrogen evolution reaction is one of the important ways to convert solar energy into renewable hydrogen. In this work, the Co 9 S 8 hollow polyhedron was formed after sulfidation and calcination with the metalorganic framework ZIF-67. The hollow polyhedron Co 9 S 8 provides abundant support sites for Mn 0.05 Cd 0.95 S and effectively reduces the agglomeration degree of Mn 0.05 Cd 0.95 S. The Co 9 S 8 hollow polyhedron as the reaction site has a large specific surface area and a mesoporous structure, which is beneficial to the progress of the photocatalytic reaction. A series of tests showed that the introduction of Co 9 S 8 hollow polyhedron significantly improved the lighttrapping ability and exposed more reaction sites. Co 9 S 8 hollow polyhedrons are used as electron capture sites, which can effectively collect electrons and induce the interface charge transfer of Mn 0.05 Cd 0.95 S to Co 9 S 8 . Because the Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst had a strong light-trapping ability, abundant reaction sites and Co 9 S 8 -Mn 0.05 Cd 0.95 S heterojunction accelerate the separation and transfer of charges. Therefore, the hydrogen evolution rate of the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst was relatively high, which was 13.369 mmol g −1 h −1 . In addition, the 10%Co 9 S 8 -Mn 0.05 Cd 0.95 S composite catalyst still has good hydrogen evolution stability after four cycles. This research may supply a new idea for the preparation of high-efficiency photocatalysts with hollow structures.Novelty Statement: The Co 9 S 8 hollow polyhedron provides abundant support sites for M 0.05 C 0.95 S particles, which effectively reduces the degree of agglomeration. The Co 9 S 8 -M 0.05 C 0.95 S heterojunction catalyst not only accelerates the migration and transfer of electrons, but also provides abundant reaction sites. Therefore, the Co 9 S 8 -M 0.05 C 0.95 S composite catalyst has good catalytic activity.

“…For the last 20 years, due to their distinctive characteristics, such as a controllable pore size, permanent porosity, high chemical/mechanical stability, elevated active surface area, and facile functionalization, MOFs have been used as adsorbents [9,10], catalysts [11,12], supercapacitors [13], and drug delivery vehicles [14,15], especially for cancer therapy purposes [16,17]. Moreover, recently, sophisticated mixed-metal MOFs [18,19], as well as surface-modified MOFs [20], BioMOFs [21,22], and MOFs-derived materials [4,23], have attracted much interest in various fields, ranging from environmental engineering to biomedicine. The high number of publications related to MOFs, coupled with a sharp increase in the number of released papers each year, exhibits the desirability to use these valuable complexes (Figure 3).…”

As hybrid porous structures with outstanding properties, metal–organic frameworks (MOFs) have entered into a large variety of industrial applications in recent years. As a result of their specific structure, that includes metal ions and organic linkers, MOFs have remarkable and tunable properties, such as a high specific surface area, excellent storage capacity, and surface modification possibility, making them appropriate for many industries like sensors, pharmacies, water treatment, energy storage, and ion transportation. Although the volume of experimental research on the properties and performance of MOFs has multiplied over a short period of time, exploring these structures from a theoretical perspective such as via molecular dynamics simulation (MD) requires a more in-depth focus. The ability to identify and demonstrate molecular interactions between MOFs and host materials in which they are incorporates is of prime importance in developing next generations of these hybrid structures. Therefore, in the present article, we have presented a brief overview of the different MOFs’ properties and applications from the most recent MD-based studies and have provided a perspective on the future developments of MOFs from the MD viewpoint.
