“…Figure 5(d) shows lower C s values at the higher current density due to the fact that electrolyte ions could not penetrate deep into electrode (active) material at the applied higher current density, giving lower specific capacitance values. Decreasing specific capacitance values with increasing current density is a general phenomenon in supercapacitor measurements because at higher scan rates and higher current density the electrolyte ions are not much accessible resulting in a decreased value of specific capacitance 41‐43 . Furthermore, the storage potential of the MoO 3 /NiO/PdO/Pd electrode was anticipated by calculating the energy density (ED; E ) (W h kg −1 ) and power density (PD; P ) (W kg −1 ) values [Fig.…”

BACKGROUNDOwing to the significance of metal oxide nanomaterials for energy storage supercapacitors, sustainable, cost‐effective and scalable synthesis of facile nanomaterials is a great challenge in the current era. Here, we have hydrothermally synthesized and functionalized a facile ternary metal oxides (MoO3/NiO/PdO/Pd) nanomaterial using the green phyto‐organic reducing plus stabilizing reagent Euphorbia cognata Boiss foliar extract (FE). The aqueous‐prepared FE was reacted with metal precursors and during this process, free octodrine and cyclobutanol organic functional groups of FE were incorporated as stabilizing agents.RESULTSThe synthesized MoO3/NiO/PdO/Pd demonstrated an optical band gap energy of 1.6 eV. Supercapacitor measurements of prepared MoO3/NiO/PdO/Pd were carried out on nickel (Ni) foam‐modified electrodes via charge–discharge (GCD), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). CV measurements have been recorded at the range of scan rates (2–300 mV s−1) and it was found that the nanocomposite‐modified Ni foam showed a specific capacitance of 257 F g−1 at a scanning rate of 2 mV s−1. Furthermore, from the GCD investigation, it was revealed that 175 F g−1 was achieved at 0.5 A g−1 with a discharge current‐based energy density of 7.2 Wh kg−1. The fabricated electrode showed a 0.4 Ω resistance value from the impedance Nyquist plot.CONCLUSIONThe study concluded that the MoO3/NiO/PdO/Pd nanocomposite with the smaller synergistic band gap and catalytic advantage of phytostabilizing agents revealed exceptional capacitive properties, validating its potential as a supercapacitor electrode. © 2023 Society of Chemical Industry (SCI).

“…Shifting their point of zero charge, these materials could be used not only for Na + removal but also, to capture Cl À via intercalation within their 2D layered structure. [154][155][156] TMDCs are also 2D materials typically with a MX 2 (X-M-X) stoichiometry in a hexagonal lattice, where M is the transition metal and X is the chalcogen (e.g. MoS 2 ).…”

“…However, the sharpness of the peaks and overall CV curvature orientation is also indicating toward the pure battery-like electrochemical functionality of the designed electrode. [44][45][46] Figure 5d shows the electrochemical response of the LRE 3þdoped Ta 2 O 5 decorated NF electrode after storing at room conditions for 20 days. CV cycles were recorded to see the stability aspect of the fabricated electrode.…”

Light rare earth (LRE3+) ions‐doped Ta2O5 semiconductor material is synthesized via coprecipitation method with the bandgap energy of 3.94–4.05 eV and an orthorhombic geometry with 74.49 nm size. The rare earth‐modified Ta2O5 improves the photovoltaic functionality of the fully ambient perovskite solar cell by efficient extraction of electrons and blocking of the holes. The device achieved an efficiency of 13.36% with 63% of fill factor and negligible hysteresis index. LRE3+ triply doped Ta2O5 is used for the fabrication of an electrode by decorating on the nickel foam. This electrode outperforms the conventionally used materials by achieving a specific capacitance of 517.5 F g−1 marked by fast reaction kinetics and diffusion with an equivalent series resistance of 0.18 Ω. LRE3+‐doped Ta2O5 is proved to be an excellent electrode material with the characteristic electric double‐layer capacitance behavior in conjugation with the Faradic pseudocapacitive behavior. Finally, the electrocatalysis using this material indicates its excellence as a H2 generating catalyst in comparison to O2 generation with the smallest overpotential and Tafel slope values of 143 mV and 125.3 mV dec−1, respectively. The designed electrode expressed an exceptional stability over ambient conditions as well as inside an electrolyte.
