“…Hence, considerable recent efforts have been devoted to design and develop noble-metal-free NRR electrocatalysts . Metal-organic frameworks (MOFs) are a class of porous polymeric material and made by metal ions linked to organic ligands [42][43][44][45]. MOFs have been extensively studied due to their extraordinarily high surface areas and abundant active sites [46].…”

As a carbon-neutral alternative to the Haber-Bosch process, electrochemical N 2 reduction enables environment-friendly NH 3 synthesis at ambient conditions but needs active electrocatalysts for the N 2 reduction reaction. Here, we report that conductive metal-organic framework Co 3 (hexahydroxytriphenylene) 2 (Co 3 HHTP 2) nanoparticles act as an efficient catalyst for ambient electrochemical N 2-to-NH 3 fixation. When tested in 0.5 M LiClO 4 , such Co 3 HHTP 2 achieves a large NH 3 yield of 22.14 μg•h-1 •mg-1 cat. with a faradaic efficiency of 3.34% at-0.40 V versus the reversible hydrogen electrode. This catalyst also shows high electrochemical stability and excellent selectivity toward NH 3 synthesis.

“…Notably, the maximum capacitance value can also be compared with that of recent reports on MOFs-based electrodes. [6][7][8]11,16,17,[30][31][32][33] These results suggest that introduction of CNTs not only inuences the exterior morphology and thus further affects the surface area, the interface effect and synergy effect of the composite, but also indeed improves the resulting electrochemical performances through its morphology discrepancy. 20,21 Aer carefully checking from the table, the second discrepancy is generated, that is, the distinct rate capability.…”

“…To date, various pure manganese oxides (MnO x ) have been directly used as electrode materials 94‐96 . Meanwhile, the pseudocapacitive properties of manganese‐organic compounds and their composites ( 1 ‐ 11 ) make them attractive materials for SC applications, 87‐93 which may result from the surface redox reactions of manganese ions in different valence states 88 . This conversion process in aqueous electrolytes can be expressed by the following equations:

Mn {(II)}_{s} + {OH}^{-} \leftrightarrow Mn ((), II) {(OH)}_{ad} + e^{-},

Mn ((), II) {(OH)}_{ad} \leftrightarrow Mn ((), III) {(OH)}_{ad} + e^{-} .

Metal‐organic compounds, including molecular complexes and coordination polymers, have attracted much attention as electrode materials in supercapacitors owing to their large surface area, high porosity, tailorable pore size, controllable structure, good electrochemical reversibility, and abundant active sites. Among the variety of metal‐organic compounds exhibiting desired supercapacitor performances (high specific capacitance, long cycling life, high energy density, and power density), those with metals in the first transition metal series are the most studied due to their rich covalent states, light atom weight, environmental‐friendliness, non‐toxicity, and low cost. In this review, the recent reports on the metal‐organic compounds of the first transition metal series as electrode materials in supercapacitors are summarized and their electrode and device performances are discussed in terms of different metal elements and typical multidentate ligands. Moreover, the current challenges, design strategies, future opportunities and further research directions are also highlighted for metal‐organic compounds in the field of supercapacitors.
