Their corrosion inhibition mechanism was investigated for the N80 steel in 3.5 % NaCl solution using different techniques, including electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), potentiodynamic polarization (PDP), density functional theory (DFT), and Monte Carlo (MC) simulations.

The spontaneous adsorption of <strong>MSeOH</strong> and <strong>[Ni(MSeO)₂(H₂O)₂]</strong> on the steel’s surface, conforming to the Langmuir adsorption isotherm, was substantiated by the increase in charge transfer resistance (R_ct) and the decrease in the constant phase element (Y₀) admittance values, evidencing the adsorption of <strong>MSeOH</strong> and <strong>[Ni(MSeO)₂(H₂O)₂]</strong> molecules on the N80 steel surface, which was further corroborated by XPS and |SEM analysis. Moreover, DFT results showed that the <strong>[Ni(MSeO)₂(H₂O)₂]</strong> complex has a high HOMO energy level, thus indicating high inhibition efficiency.

LRLOs suffer from irreversible capacity loss, poor rate capability, voltage, and capacity fade, which in turn limit their full practical applications and commercialization. Therefore, strategies such as surface coating, surface treatment, composition optimization, and elemental doping have been explored to enhance the structural and electrochemical performance of LRLO. Nevertheless, high entropy (multiple elements) doping has proven to be a very effective strategy due to its simplicity and expansion of LRLO lattice interplanar spacing without damaging their original structure. It is worth noting that there has been little research work on high entropy strategies for modifying LRLO cathode.

X-ray diffraction analysis of the doped nanoparticles at different percentages confirmed the monoclinic structure of the synthesized Ag doped α-Zn₂V₂O₇ nanoparticles. The average crystallite size, calculated using Scherrer’s formula, was observed to increase with the rise in doping percentage. The morphological properties of the nanoparticles were analyzed through SEM analysis. EDAX spectra confirmed the presence of Ag, Zn, V, and O in the prepared nanoparticles. XPS survey of the prepared sample revealed the presence of Ag, Zn, O, and V without any impurities, except for a small amount of absorbed carbon, and the spectra also confirmed that the sample consisted of a phase of Ag-doped Zn₂V₂O₇. The reduction of band gap values with the increase in doping percentage was identified through UV–visible spectrophotometer investigation. The broad peak of PL emission spectra in the green wavelength region suggested the creation of deep energy levels inside the band gap of the nanoparticles. The photocatalytic activity of the synthesized sample in the degradation of methylene blue dye under sunlight was studied using a UV–visible spectrometer.
