“…The broadened double peaks at 233.1 eV and 235.6 eV are attributable to the electronic binding energies of Mo 3d 3/2 and Mo 3d 5/2 of Mo 6+ in α-MoO 3 -S (Fig. 3b), 45,46 and the shifting binding energies towards a higher value are observed compared to α-MoO 3 -B, indicating the changing chemical environment of Mo before and after the exfoliation of α-MoO 3 . Specifically, the Mo 3d core level of exfoliated α-MoO 3 -S affords the lower electron cloud density corresponding to a higher Mo valence than that of α-MoO 3 -B, which could result from the treatment of H 2 O 2 and the hydrothermal process.…”

“…In the next step, these two substrates were kept in a beaker containing 5.0 M KOH. The manufactured MBFO-NC//MBFO-NC replica electrodes were connected to a laboratory plate (BM), whereby the MBFO-NC//MBFO-NC replica electrode was used for a practical application of the electrode material for the illumination of the BM, which contains 31 LEDs as shown in Figure d. This shows how crucial the use of the manufactured symmetric cell electrodes MBFO-NC//MBFO-NC is in portable electronic devices for daily use …”

Bismuth ferrite (BiFeO 3 ) is regarded as an important ABO 3 perovskite in the areas of energy storage and electronics. A high-performance novel MgBiFeO 3 -NC nanomagnetic composite (MBFO-NC) electrode was prepared using a perovskite ABO 3 -inspired method as a supercapacitor for energy storage. The electrochemical behavior of the perovskite BiFeO 3 has been enhanced by magnesium ion doping in the basic aquatic electrolyte as the A-site. H 2 -TPR revealed that the doping of Mg 2+ ions at the Bi 3+ sites minimizes the oxygen vacancy content and improves the electrochemical characteristics of MgBiFeO 3 -NC. Various techniques were used to confirm the phase, structure, surface, and magnetic properties of the MBFO-NC electrode. The prepared sample showed an enhanced mantic performance and specific area with an average nanoparticle size of ∼15 nm. The electrochemical behavior of the three-electrode system was shown by cyclic voltammetry to have a significant specific capacity of 2079.44 F/g at 30 mV/s in 5 M KOH electrolyte. GCD analysis at a 5 A/g current density also showed an enhanced capacity improvement of 2159.88 F/g, which is 3.4× higher than that of pristine BiFeO 3 . At the power density of 5284.83 W/kg, the constructed MBFO-NC//MBFO-NC symmetric cell showed an exceptional energy density of 730.04 W h/kg. The MBFO-NC//MBFO-NC symmetric cell was employed as a direct practical application of the electrode material to entirely brighten the laboratory panel, which had 31 LEDs. This work proposes the utilization of duplicate cell electrodes made of MBFO-NC//MBFO-NC in portable devices for daily use.

“…229 The interfacial regions of heterogeneous structures can provide opportunities to enrich the number of active sites 230 and promote electron transfer. 231,232 And strong electronic interactions in the heterogeneous interfaces facilitate the enhancement of electronic and ionic conductivity 233 and redox reaction kinetics. 234 However, the tightness of the heterogeneous interface is difficult to control, and the existence of voids between the interfaces affects the electrochemical properties.…”
