The present work demonstrated a novel Cleome simplicifolia -mediated green fabrication of nickel oxide nanoparticles (NiO NPs) to explore in vitro toxicity in Bm-17 and Labeo rohita liver cells. As-fabricated bioinspired NiO NPs were characterized by several analytical techniques. X-ray diffraction (XRD) revealed a crystalline face-centered-cubic structure. Fourier transform infrared spectroscopy (FTIR), ultraviolet–visible diffuse reflectance spectroscopy (UV-DRS), Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS) confirmed NiO formation. The chemical composition was confirmed by energy-dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy. Brunauer–Emmett–Teller (BET) revealed the mesoporous nature. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) revealed the formation of 97 nm diameter nanospheres formed due to the congregation of 10 nm size particles. Atomic force microscopy (AFM) revealed the nearly isotropic behavior of NiO NPs. Further, a molecular docking study was performed to explore their toxicity by binding with genetic molecules, and it was found that the docking energy was about −9.65284 kcal/mol. On evaluating the in vitro toxicity of NiO NPs for Bm-17 cells, the study showed that when cells were treated with a high concentration of NPs, cells were affected severely by toxicity, while at a lower concentration, cells were affected slightly. Further, on using 50 μg/mL, quick deaths of cells were observed due to the formation of more vacuoles in the cells. The DNA degradation study revealed that NiO NPs are significantly responsible for DNA degradation. For further confirmation, trypan blue assay was observed for cell viability, and morphological assessment was performed using inverted tissue culture microscopy. Further, the cytotoxicity of NiO NPs in L. rohita liver cells was studied. No toxicity was observed at 1 mg/L of NiO NPs; however, when the concentration was 30 and 90 mg/L, dark and shrank hepatic parenchyma was observed. Hence, the main cause of cell lysis is the increased vacuolization in the cells. Thus, the present study suggests that the cytotoxicity induced by NiO NPs could be used in anticancer drugs.

“…For Co 3 O 4 @ NC/NiO, three small diffraction peaks are observed at 37.9° (111), 43.2° (200), and 63.6° (220), confirming the formation of NiO from Ni(OH) 2 as per JCPDS No. 65-2901 because the heat treatment led to the removal of H 2 O molecules and decomposition of Ni(OH) 2 [56,57] (Figure 3b). The heat treatment at 700 °C resulted in the Co-MOF-templated formation of Co 3 O 4 nanoparticles embedded with N-doped carbon on NiO; the diffraction peaks at 31.1° (220), 35.6° (311), and 66.3° (440) coincide with the XRD pattern of JCPDS Card no.…”

Metal–organic framework (MOF)‐derived electrocatalysts exhibit enhanced electrochemical water splitting with significant durability. However, they cannot drive the required current density at a lower overpotential (η) compared to other benchmark catalysts. To overcome the lack of efficient catalytic activity, Co3O4‐embedded nitrogen‐doped carbon (NC) is fabricated on NiO nanosheets derived from an in situ synthesized Co MOF with an electrodeposited (Ni(OH)2) layer. The electrocatalyst developed herein comprises many Co3+, Ni3+, and pyridinic‐N‐exposed active centers and exhibits an excellent synergistic effect between the metal oxide–NC–metal oxide, facilitating a highly efficient hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). Owing to the highly intimate contact between the electrocatalyst layers, rapid electron transfer occurs and a current density of 10 mA cm‐2 is produced in the HER and OER at η of 73 and 110 mV, respectively, with excellent mass activity and high turnover frequency. However, urea‐assisted water electrolysis achieves current densities of 10 and 100 mA cm‐2 at cell voltages of just 1.31 and 1.49 V, respectively, for the two‐electrode‐based system, with an extremely stable durability of 212 h (1.49 V). Co3O4@NC/NiO ∥ Co3O4@NC/NiO has a considerably better urea electrolysis performance than other benchmark electrocatalysts.

“…As is well known, owing to the low initial Coulombic efficiency and capacity of carbon materials, exploring carbon-free electrode materials has been deemed as a hotspot worth studying. Therefore, significant progress has been made in the system of NiO@metallic oxide, including Fe 2 O 3 54 , TiO 2 , , Co 3 O 4 , − MnCo 2 O 4 59 , NiCo 2 O 4 , , NiFe 2 O 4 62 , and ZnCo 2 O 4 63 . TiO 2 , as a “zero-strain” material, acted as a template for the growth of NiO, resulting in the regular distribution of NiO. , As shown in Figure f, Zhang et al reported that hierarchical nonwoven fabric NiO/TiO 2 films act as an anode material for lithium-ion batteries.…”

Captured by the high energy density and eco-friendly properties, secondary energy-storage systems have attracted a great deal of attention. For meeting with the demand of advanced systems with both cycling stability and high capacity, a series of tailoring methods have been used. Electrode materials, as the main components of a full cell, play importance roles in capacity contribution. Thus, exploring suitable materials has been deemed to be vital for the development of energy-storage systems. Recently, compared to the traditional carbon-based materials, the considerable electrochemical properties of metal-based samples have been observed. Alternatively, nickel-based materials displayed resource abundance, environmental-friendliness, and high theoretical specific capacity, while the rich exploring activities have been scarily summarized. In this review, the energy-storage performances of nickel-based materials, such as NiO, NiSe/NiSe2, NiS/NiS2/Ni3S2, Ni2P, Ni3N, and Ni(OH)2, are summarized in detail. For some materials with innovative structures, their merits and characteristics were discussed elaborately through four points: (1) the controlling of nanostructures, (2) the complexing of carbon materials, (3) the doping of heteroatoms, and (4) the designing of heterostructures. Significantly, the challenges and prospects of nickel-based materials for secondary battery systems are discussed. This work is expected to offer significant summarization and prospects about physical–chemical designing for nickel-based samples.
