“…In addition to the diffraction peaks of NF and Ni 3 S 2 , other diffraction peaks (marked with “♤”) were detected at 19.3°, 33.1°, 38.5°, 52.1°, 59.1°, 62.7°, and 72.6°, corresponding to the (001), (100), (101), (102), (110), (111), and (201) planes of Ni(OH) 2 , respectively (JCPDS, No:00-014-0117). Yang et al [ 35 ] failed to observe the characteristic peaks of Ni-MOF (at 15.7°, 18.4°, and 23.7°), indicating that all Ni-MOFs were completely converted to Ni(OH) 2 . The diffraction peaks related to Ni 3 S 2 and Ni(OH) 2 were comparatively weak due to their lower content compared with that of the NF substrate.…”

Honeycomb-like Ni(OH)2/Ni3S2/Ni foam (NF) was fabricated via a two-step hydrothermal process and subsequent alkalization. Ni3S2 with a honeycombed structure was in-situ synthesized on the NF surface by a hydrothermal process. MOF-derived Ni(OH)2 nanosheets were then successfully grown on the Ni3S2/NF surface by a second hydrothermal process and alkaline treatment, and a large number of nanosheets were interconnected to form a typical honeycomb-like structure with a large specific surface area and porosity. As a binder-free electrode, the prepared honeycomb-like Ni(OH)2/Ni3S2/NF exhibited a high specific capacitance (2207 F·g−1 at 1 A·g−1, 1929.7 F·g−1 at 5 mV·s−1) and a remarkable rate capability and cycling stability, with 62.3% of the initial value (1 A·g−1) retained at 10 A·g−1 and 90.4% of the initial value (first circle at 50 mV·s−1) retained after 5000 cycles. A hybrid supercapacitor (HSC) was assembled with Ni(OH)2/Ni3S2/NF as the positive electrode and activated carbon (AC) as the negative electrode and exhibited an outstanding energy density of 24.5 Wh·kg−1 at the power density of 375 W·kg−1. These encouraging results render the electrode a potential candidate for energy storage.

Metal‐Organic Frameworks (MOFs), a novel class of porous extended crystalline structures, are favored in different fields of heterogeneous catalysis, CO2 separation and conversion, and energy storage (supercapacitors) due to their convenience of synthesis, structural tailor‐ability, tunable pore size, high porosity, large specific surface area, devisable structures, and adjustable compositions. Nickel (Ni) is a ubiquitous element extensively applied in various fields of catalysis and energy storage due to its low cost, high abundance, thermal and chemical stability, and environmentally benign nature. Ni‐based MOFs and their derivatives provide us with the opportunity to modify different properties of the Ni center to improve their potential as heterogeneous catalysts or energy storage materials. The recent achievements of Ni−MOFs and their derivatives as catalysts, membrane materials for CO2 separation and conversion, electrode materials and their respective performance have been discussed in this review.

“…Nevertheless, the capacitance value of NiTe is very low and not sufficient for SC applications . Compounding is an effective method of modulating the electron structure to provide additional redox reactions. − Antimony metal shows superior electrochemical performance in the application of energy storage thanks to its good electrical conductivity (1.6 × 10 4 S m –1 ), high theoretical capacitance value (660 mA h g –1 ), and fast ionic diffusion property. , Composite Sb compounds can tune the overall electrical conductivity and take advantage of the respective capacitive contribution and the synergistic effect of multiple active species, resulting in higher specific capacities. − For example, Usui et al prepared CeO 2 /Sb 2 O 3 composites for sodium storage by mechanical grinding. The CeO 2 /Sb 2 O 3 composite electrode exhibited 400 mA h g –1 capacity during the 120th cycle, greatly improving the capacity compared to the low capacity of CeO 2 (25 mA h g –1 ) during the first charge/discharge process.…”

In this paper, NiSb/NiTe/Ni composites were smoothly developed via the microwave method for supercapacitors. The synthesis of NiSb/NiTe crystals was revealed by X-ray photoelectron spectroscopy and X-ray diffraction. The analytic results of scanning electron microscopy and energy dispersive spectroscopy uncover the microscopic morphology as well as the constituent elements of the composites. Self-supported NiSb/NiTe is a supercapacitor cathode that combines high capacitance with excellent cycling stability. The obtained composite electrode displayed remarkable electrochemical properties, presenting a special capacitance of 1870 F g −1 (1 A g −1 ) and 81.5% of the original capacity through 30,000 times (10 A g −1 ) of the charging/ discharging process. Further, an asymmetric supercapacitor was prepared employing NiSb/NiTe as a cathode and activated carbon as an anode. NiSb/NiTe//AC exhibited a high energy density of 224.6 uW h cm −2 with a power density of 750 μW cm −2 and provided a favorable cycling stability of 83% after 10,000 cycles.
