“…To enhance the electroconductibility of pure MOFs, some authors incorporated another metallic element into the MOF structure to fabricate hybrid and mixed metal ion MOF structures. [22][23][24] To further enhance the conductivity of even hybrid MOFs, it is possible to fabricate MOFs composites by combining them with more conductive and stable materials, for example, carbon nanotubes (CNTs), 25 graphene nanoplatelets (GNPs) and graphene oxides (GO). 26 Use of such sophisticated materials has been proven beneficial because they possess intrinsic higher conductivity values and distinctive structures.…”

Solvothermal synthesis of Ni-Co-MOF/graphene nanoplatelets (GNPs) nanocomposites was done for their potential application as electrode material in energy storage devices. Addition of GNPs and metallic precursors together with 2-methylimedazole in the same autoclave reactor produced smooth-nanoflakes like Ni-Co-MOF/GNPs nanocomposites as evaluated by SEM. XRD analysis showed the presence of GNPs where GNPs do not affect the growth of MOF crystals and Ni-Co-MOF crystalline phases remain unaffected in the composite structure. FTIR analysis confirmed the presence of organic links forming nickel-cobalt metal cations framework. Electrochemical testing(CV,EIS,GCD) of the produced composites demonstrated that GNPs addition can enhance the charge storage performance of MOFs nanocomposites. The largest cycle area and most discharge time have been shown by Ni-Co-MOF/GNP-50 composite electrode that delivered the highest specific capacity values (313 Cg-1@1 Ag-1), good reversibility and low internal resistance and charge transfer resistance. Moreover, Ni-Co-MOF/GNP-50 composite exhibited good thermal stability with 28% weight loss during thermogravimetric analysis. The electrochemical evaluations performed on asymmetric supercapacitor real device expressed a specific capacity of 136.5 Cg-1@0.5 Ag-1, maximum energy density of 32.2 Whkg-1@425 Wkg-1 and maximum power density of 17000 Wkg-1@12.8 Whkg-1. Moreover, the device showed a stability performance of 92.5%@10 Ag-1 after 5000 CD cycles.

“…Further studies include, Zn-Co-MOF@CuO composite presented a capacity of 308 C g -1 at 2 A g -1 maintained to 220 C g -1 , even at 20 A g -1 [9]. Ni/Zn bi-metallic CSN prepared through a hydrothermal approach showed 210 C g -1 at 0.5 A g -1 [10]. Among the different MOFs employed in these studies, Ni and Co-based materials have very good results owing to their small ionic radii (69 pm and 74.5 pm, respectively), which results in easy diffusion as compared to the other metals [11,12].…”

Hybrid metal-organic frameworks (MOFs) have many positive features like high porosity, surface area, and conductivity as compared to other materials. They have better potential than pristine ones due to the reason that hybrid materials have good faradic responses due to variable metal oxidation states. These all-favorable factors make hybrid MOFs more potential electrodes for energy storage. In this study, hybrid Ni-Co MOFs presented good specific capacitance of 745 F g-1 (447 C g-1 @ 1 A g-1) in comparison with pristine Co MOFs of 109 F g-1 (65.5 C g-1 @ 1 A g-1). Also, the hybrid MOFs showed superior electrical conductivity of 1353.3 S cm-1 as compared to pristine MOFs. The charge transfer resistance (Rct) of hybrid MOFs was 2.271 Ω pretty much greater than pristine MOF and other closely related studies. The best electrochemical performance was attributed to the synergic effect of Ni, Co, and organic ligand.

“…The Zn( ii ) coordination polymers (CPs) have been widely explored as an important family of compounds with high diversity of structures, 1–6 remarkable functional properties, 7–9 and applications in photochemistry, 10,11 sensing, 12–16 gas sorption, 17–19 energy storage, 20–23 and catalysis, 24–27 just to name a few. This is also governed by some features of zinc( ii ) ions and derived compounds, such as low cost and abundance, bio- and photoactivity, and rich coordination chemistry toward a broad spectrum of ligand types.…”
