“…The V–N–C SACs were developed through a sacrificial template strategy. First, the template NH 2 -MIL-101(V) was synthesized by a solvothermal process according to the procedure reported in one of our previous studies . Then, NH 2 -MIL-101(V) powders (0.5 g) were pyrolyzed at the desired temperature under a N 2 gas atmosphere (80 mL/min).…”

“…Herein, we report a rational design and synthesis of N atoms coordinated to V sites that are atomically distributed in a hierarchically porous carbon network through the annealing of a V-based MOF with subsequent acid etching. To generate this material, an MOF [NH 2 -MIL-101(V)] comprising V 3+ ions and nitrogen-containing linkers, that is, 2-aminoterephthalic acid (NH 2 -BDC), is used as the precursor owing to its inherent vanadium content, highly mesoporous network, and N-rich ligands. , After carbonization under a N 2 atmosphere, the nitrogen atoms in NH 2 -MIL-101(V) and the metal V atoms react to form strong V–N bonds. After a subsequent acid-etching treatment, residual unstable species are completely removed, and the V-based residues that are inlaid in the hierarchically porous carbon framework predominantly exist as isolated single atoms trapped by N atoms (denoted as V–N–C) with enhanced thermal and chemical stability.…”

Single-atom catalysts effectively integrate the respective advantages of homogeneous and heterogeneous catalysts and are a pioneering research frontier in catalysis by virtue of their maximized utility of metal atoms and distinct atomic configuration. However, development of such catalysts is still in the early stages. Herein, atomically dispersed vanadium (V) sites that are coordinated by N atoms and inlaid within N-incorporated porous carbon networks were prepared through a top-down strategy by annealing a V-containing metal−organic framework, NH 2 -MIL-101(V), followed by acid etching. The resulting V−N− C-600 catalyst exhibits unexpected catalytic reactivity, selectivity, and robust stability for the direct aerobic oxidation of benzylamine to generate N-benzylidene benzylamine with molecular oxygen under mild conditions. The turnover frequency reaches 53.9 h −1 , which is much superior to those achieved over the commercial V 2 O 5 and state-of-the-art non-noble metal heterogeneous catalysts reported in the literature. Kinetic analysis reveals a low activation energy barrier (37 kJ mol −1 ) for the benzylamine oxidation and indicates that a carbocationic intermediate is involved in the reaction mechanism. The synergistic effect between the isolated V single-atomic sites and N-doped hierarchically porous carbon network boosts the performance of V−N−C-600. Moreover, V−N−C-600 exhibits a wide generality for the efficient synthesis of a set of symmetrical imines, unsymmetrical imines, and imine derivatives.

“…In comparison with MIL-101 (V), the amino-modified MIL-101 (NH 2 -MIL-101) do not only have a larger specific surface area, but also demonstrate higher CO 2 /N 2 adsorption capacity and moderate CO 2 isosteric heat of adsorption. 106 Moreover, the steric resistance and physical property of the substituent for the ligands also have certain influence on the construction of MOFs.…”

With the excessive consumption of nonrenewable resources, the exploration of effective and durable materials is highly sought after in the field of sustainable energy conversion and storage system. In this aspect, metalorganic frameworks (MOFs) are a new class of crystalline porous organicinorganic hybrid materials. MOFs have recently been gaining traction in energy-related fields. Owing to the coordination flexibility and multiple accessible oxidation states of vanadium ions or clusters, vanadium-MOFs (V-MOFs) possess unique structural characteristics and satisfactory electrochemical properties. Furthermore, V-MOFs-derived materials also exhibit superior electrical conductivity and stability when used as electrocatalysts and electrode materials. This review summarizes the research progress of V-MOFs (inclusive of pristine V-MOFs, V/M-MOFs, and POVbased MOFs) and their derivatives (vanadium oxides, carbon-coated vanadium oxide, vanadium phosphate, vanadate, and other vanadium doped nanomaterials) in electrochemical energy conversion (water splitting, oxygen reduction reaction) and energy storage (supercapacitor, rechargeable battery). Future possibilities and challenges for V-MOFs and their derivatives in terms of design and synthesis are discussed. Lastly, their applications in energy-related fields are also highlighted.

“…MIL-101 was originally built from the trivalent chromium ion (Cr 3+ ) along with the ditopic 1,4-benzene dicarboxylic acid linker (H 2 BDC, commercially called terephthalic acid or TPA), yielding a mesoporous structure of Mobil thirty-nine (MTN) zeolite topology. 8 Later on, isostructural analogues were synthesized using other trivalent metal cations like Fe 3+ , [9][10][11][12] Al 3+ , [13][14][15] V 3+ , [16][17][18] Ti 3+ , 19,20 and Sc 3+ . 21,22 On the other side, several BDC linkers with different functional groups were incorporated in these syntheses targeting various functionalities.…”
