“…), in MOFs, the anionic species is replaced by an organic linker [ 6 ]. It should be noted that MOF nodes with unique elements from across the periodic table have also been synthesized [ 11 , 12 , 13 ]. This variation in nodes typically impacts analyte affinity to induce electrostatic interactions as well as the thermal and chemical stability of the MOF.…”

Metal–organic-frameworks (MOFs) are emerging materials used in the environmental electrochemistry community for Faradaic and non-Faradaic water remediation technologies. It has been concluded that MOF-based materials show improvement in performance compared to traditional (non-)faradaic materials. In particular, this review outlines MOF synthesis and their application in the fields of electron- and photoelectron-Fenton degradation reactions, photoelectrocatalytic degradations, and capacitive deionization physical separations. This work overviews the main electrode materials used for the different environmental remediation processes, discusses the main performance enhancements achieved via the utilization of MOFs compared to traditional materials, and provides perspective and insights for the further development of the utilization of MOF-derived materials in electrified water treatment.

“…Benefiting from the modifiability of organic ligands and the inherent optical, electrical, and magnetic properties of different metal ions, MOFs not only have variable structures but also can exhibit different properties, and therefore have potential applications in many fields. Amongst all the applications, photocatalysis is one of the most important fields due to its commitment to the development of solar energy [62–65] . Up to now, MOF‐based materials have exhibited high photocatalytic activity for a lot of reactions, including photocatalytic removal of environmental pollutants (industrial and emerging contaminants, gaseous air pollutants), photocatalytic oxidation of amines and alcohols, photocatalytic water splitting and hydrogen production, CO 2 photoreduction, and so on [66–73] .…”

“…Recently, light‐driven nitrogen fixation for ammonia synthesis catalyzed by MOFs has received more attention. In contrast to metal oxides, metal sulfides, BiOX (X=Cl, Br, I), and carbonaceous materials, MOFs have been considered to ideal candidates for nitrogen fixation photocatalyst due to the following advantages: [66–71,74–78] 1) The porous structure of MOFs allows nitrogen to participate in the reduction reaction in the pore channels, thereby shortening the transmission distance of photo‐generated electrons and improving the photocatalytic efficiency. 2) Both metal centers and organic ligands in MOFs present high adjustability.…”

Solar‐driven photocatalytic nitrogen fixation is a low‐energy and environmentally friendly strategy for NH3 synthesis, which is considered as a possible alternative to the Haber‐Bosch (HB) process. Considering the extremely high bond energy of N2, the choice of photocatalysts is essential for nitrogen reduction reaction (NRR). As a class of porous materials with high crystallinity and adjustable organic ligands, metal‐organic frameworks (MOFs) have been proven to exhibit high photocatalytic activity for a lot of reactions. Recently, MOFs and MOF‐based functional materials have become a kind of promising photocatalysts for NRR. In this minireview, we provide a comprehensive overview of the work reported so far on the MOF and MOF‐derived photocatalysts for the nitrogen fixation. Through the comprehensive analysis of the structures, nitrogen fixation performances and mechanisms of these photocatalysts, this minireview provides a reference for the design of new photocatalysts based on MOF materials.

“…[4] MOFs exhibit high photocatalytic activity for important processes, such as organic degradation and transformation, water splitting and hydrogen production, and CO 2 reduction, all of which take advantage of modifiable organic ligands and properties of different metal nodes. [5] However, reports of solar-driven NRR for ammonia synthesis catalyzed by MOFs remain rare, [6] and MOFs photocatalytic NRR pathways and structure-activity relationships remain unclear. Compared with traditional nitrogen fixation photocatalysts, such as metal oxides, metal sulfides, BiOX and carbonaceous materials, MOFs have potential advantages, such as high crystallinity, porous structures and adjustable organic ligands for improving photocatalytic efficiency.…”

Herein we present a new viologen-based radicalcontaining metal-organic framework (RMOF) Gd-IHEP-7, which upon heating in air undergoes a single-crystal-to-singlecrystal transformation to generate Gd-IHEP-8. Both RMOFs exhibit excellent air and water stability as a result of favorable radical-radical interactions, and their long-lifetime radicals result in wide spectral absorption in the range 200-2500 nm. Gd-IHEP-7 and Gd-IHEP-8 show excellent activity toward solar-driven nitrogen fixation, with ammonia production rates of 128 and 220 mmol h À1 g À1 , respectively. Experiments and theoretical calculations indicate that both RMOFs have similar nitrogen fixation pathways. The enhanced catalytic efficiency of Gd-IHEP-8 versus Gd-IHEP-7 is attributed to intermediates stabilized by enhanced hydrogen bonding.
