“…[ 50 ] Supercapacitors or batteries with such current densities may be useful in energy storage applications, particularly if the emphasis is on energy capacity or stability rather than high current output. [ 51 ] Moreover, these electrodes could be utilized in electrocatalysis or surface alteration procedures, where the focus is on precise control over reactions and specific functionalities. Figure 4C shows the electrode's remarkable cycle stability, emphasizing its durability and usefulness for energy storage systems.…”

The objective of this study is to thoroughly investigate the synthesis and application of a thin film MnS2:CoS:Al2S3. To produce the thin film, diethyldithiocarbamate as a source of sulphur through a technique called physical vapour deposition was utilized. A wide range of analytical techniques were used to examine the structural, morphological, and optical properties of the fabricated material. X‐ray diffraction (XRD) analysis revealed the crystallite size 26.4 nm with a crystallinity of 77%. The optical properties determined the band gap energy to be 4.02 eV. Cabbage‐like assemblies were confirmed through scanning electron microscopy (SEM). X‐ray photoelectron spectroscopy unveiled distinct core level peaks associated with Mn 2p, Al 2p, Co 2p, and S 2p. To evaluate the electrochemical properties of the material, voltammetry measurements were conducted. The results from these experiments revealed an exceptional specific capacitive performance with a value of 792.6 Fg−1. This outstanding performance, coupled with the notable stability of the thin film during multiple cycles, positions it as a highly promising candidate for various energy storage applications. Furthermore, an extensive investigation was carried out to assess the photocatalytic capabilities of the fabricated material. Its efficiency in degrading different environmental pollutants was carefully evaluated.

“…Hence, SCs can be classified into two categories: pseudocapacitors with faradic charge storage and electrical double-layer capacitors (EDLC) with nonfaradic charge storage ( Ambare et al, 2015 ; Huang et al, 2020 ). In general, SCs based on carbon nanomaterials including carbon nanotubes, graphene oxides, and activated carbon (AC) are EDLCs, which have huge surface areas and strong electrical conductivity ( Chen et al, 2019 ; Iqbal et al, 2022 ). Contrarily, pseudocapacitive materials are made from transition metal oxides (TMOs), such as RuO 2 , Fe 3 O 4 , Mn 3 O 4 ( Chen et al, 2013 ), NiO, Co 3 O 4 ( Aadil et al, 2020a ; Habtu et al, 2022 ), V 2 O 5 , and ZnO, which undergo reversible faradic reactions.…”

Although cobalt oxides show great promise as supercapacitor electrode materials, their slow kinetics and low conductivity make them unsuitable for widespread application. We developed Ni and Cu-doped Co3O4 nanoparticles (NPs) via a simple chemical co-precipitation method without the aid of a surfactant. The samples were analyzed for their composition, function group, band gap, structure/morphology, thermal property, surface area and electrochemical property using X-ray diffraction (XRD), ICP-OES, Fourier transform infrared (FTIR) spectroscopy, Ultraviolet-visible (UV-Vis), Scanning electron microscopy (SEM), Thermogravimetric analysis (TGA) and/or Differential thermal analysis (DTA), Brunauer–Emmett–Teller (BET), and Impedance Spectroscopy (EIS), Cyclic voltammetry (CV), respectively. Notably, for the prepared sample, the addition of Cu to Co3O4 NPs results in a 11.5-fold increase in specific surface area (573.78 m2 g−1) and a decrease in charge transfer resistance. As a result, the Ni doped Co3O4 electrode exhibits a high specific capacitance of 749 F g−1, 1.75 times greater than the pristine Co3O4 electrode’s 426 F g−1. The electrode’s enhanced surface area and electronic conductivity are credited with the significant improvement in electrochemical performance. The produced Ni doped Co3O4 electrode has the potential to be employed in supercapacitor systems, as the obtained findings amply demonstrated.
