Abstract Metal–organic frameworks (MOFs) represent a relatively new family of materials that attract lots attention thanks to their unique features such as hierarchical porosity, active metal centers, versatility linkers/metal nodes, and large surface area. Among the extended list MOFs, Zr‐based‐MOFs demonstrate comparably superior chemical thermal stabilities, making them ideal candidates for energy environmental applications. As Zr‐MOF, NU‐1000 is first synthesized at Northwestern University. A comprehensive review various approaches synthesis MOFs obtaining properties (e.g., diverse morphologies, area, particular pore size distribution) applications in catalysis (electro‐, photo‐catalysis), CO 2 reduction, batteries, hydrogen storage, gas storage/separation, other fields are presented. The further outlines current challenges development derivatives practical applications, revealing areas future investigation.

Photocatalytic H2 evolution has recently attracted much attention due to the reduction of nonrenewable energy sources and increasing demand for renewable sustainable energies. Meanwhile, metal-organic frameworks (MOFs) are emerging potential photocatalysts their structural adaptability, porous configuration, several active sites, a wide range performance. Nevertheless, there still limitations in photocatalytic reaction MOFs with higher charge recombination rates. Herein, copper-organic framework dual-functionalized linkers {[Cu2(L)(H2O)2]·(5DMF)(4H2O)}n (fluorinated MOF(Cu)-NH2; H4L = 3,5-bis(2,4-dicarboxylic acid)-4-(trifluoromethyl)aniline) rare 2-nodal 4,12-connected shp topology been synthesized by ligand-functionalization strategy evaluated production overcome this issue. According results, fluorinated MOF(Cu)-NH2 showed hydrogen rate 63.64 mmol·g-1·h-1 exposed light irradiation, indicating values 12 times that pure ligand when cocatalyst Pt photosensitizer Rhodamine B were present. In addition, MOF maximum water absorption 205 cm3·g-1. When introduced structure MOF, its visible-light increases considerably, which can be associated nearly narrower band gaps (2.18 eV). More importantly, contributes electron collection transport, acting as bridge helps separate transfer photogenerated charges while shortening migration path because functional group configuration. The current paper seeks shed on design advanced no calcination production.
