“…Compared with typical porous materials, MOFs have exceptional tunability, well‐defined porous architectures, and ultrahigh surface areas, these benefits can fulfill the requirements for stabilizing SACs. [ 146–150 ] Based on the location of single‐atom metals within MOFs, MOFs supported SACs can be classified as: 1) single‐atom metals trapped inside the uniform pore structure of MOFs [ 151 ] ; 2) single‐atom metals connected to the unsaturated metal nodes of MOFs [ 152 ] ; 3) single atom metals chelated to the linker of MOFs.

Single‐atom catalysts (SACs) are desirable in environmental catalysis due to environmental friendliness, structural stability, and maximum utilization of active metal sites. Extensive research has compared the catalytic performance between SACs with different single‐atom metals. However, their catalytic performance is also highly dependent on the supports, which play an important role in modulating the local coordination environment of SACs. Unfortunately, a comprehensive review that systematically discusses the relationship between supports and the coordination environment, as well as their combined effects on environmental catalysis is scare. In this review, three widely investigated environmental applications including advanced oxidation processes (AOPs), mainly Fenton and Fenton‐like reactions, and nitrate reduction reaction (NO3RR) are focused. By correlating characterization results, catalytic performances, and computational results, the combined effects of supports and coordination environments on the catalytic reactivity of SACs are examined in detail, from which the origin of the catalytic pathways of AOPs as well as NO3RR is attempted to reveal. Finally a look forward for potential opportunities and challenges of SACs for on‐demand environmental applications, is provided.

“…To convert CO 2 into valuable products such as CO and CH 4 , the high bond cleavage energy is required for the highly chemical stabile carbon dioxide. 179,180 g-C 3 N 4 and a Cu-porphyrin metal−organic framework (MOF) was fabricated and used for photocatalytic reduction of CO 2 to CO and CH 4 during aerobic pretreatment. O 2 was reduced and produced hydroxyl, resulting in Cu of MOF receiving hydroxyl to generate hydroxylated Cu.…”

Catalysts played a crucial role in advancing modern human civilization, from ancient times to the industrial revolution. Due to high cost and limited availability of traditional catalysts, there is a need to develop cost-effective, high-activity, and nonprecious metal-based electrocatalysts. Metal−organic frameworks (MOFs) have emerged as an ideal candidate for heterogeneous catalysis due to their physicochemical properties, hybrid inorganic/organic structures, uncoordinated metal sites, and accessible organic sections. MOFs are high nanoporous crystalline materials that can be used as catalysts to facilitate polymerization reactions. Their chemical and structural diversity make them effective for various reactions compared to traditional catalysts. MOFs have been applied in gas storage and separation, ion-exchange, drug delivery, luminescence, sensing, nanofilters, water purification, and catalysis. The review focuses on MOF-enabled heterogeneous catalysis for value-added compound production, including alcohol oxidation, olefin oligomerization, and polymerization reactions. MOFs offer tunable porosity, high spatial density, and single-crystal XRD control over catalyst properties. In this review, MOFs were focused on reactions of CO 2 fixation, CO 2 reduction, and photoelectrochemical water splitting. Overall, MOFs have great potential as versatile catalysts for diverse applications in the future.
