“…The shift of diffraction peaks towards lower theta value might be attributed to unit cell expansion owning to ionic radius mismatch. [33] Additionally, the change illustrated doping of bismuth into lead oxide. Bismuth incorporation into lead oxide resulted in wider and less strong peaks, suggesting the inhibition of crystal formation.…”

In this study, we have reported the synthesis of both pure and bismuth‐doped lead oxide nanoparticles using solvothermal method. The synthesized nanomaterials were analyzed to assess their structure, crystallinity, phase, maximum absorption and band gap. The electrical characteristics of the fabricated nanostructures were evaluated using cyclic voltammetry (CV) and electron impedance spectroscopy (EIS). The maximum specific capacitance and energy density, 349.96 F/g and 95.27 Wh/g respectively, were attained at a scan rate of 200 mV/s in pure lead oxide. The synthesized pure lead oxide has displayed remarkable cyclic stability, retaining approximately 83 % of its performance even after undergoing 2000 cycles. The addition of bismuth to the lead oxide appeared to inhibit the electrochemical properties of lead oxide due to bismuth ion adsorption. This effect is directly concerned with the amount of dopant which predicted the increase in bismuth contents potentially suppressed the performance of the lead oxide. Our study provides insights into the possible uses of lead oxides in energy storage and conversion devices by revealing a previously unexplored method for optimizing their electrochemical characteristics. The understanding of oxide‐based materials in materials science and electrochemistry is expected to advance with the use of this novel technology.

In general, SPION@SiO 2 @ZnO and SPION@SiO 2 @TiO 2 are very similar; however, the difference in their degradation rate stems from the fact that SPION@SiO 2 @TiO 2 has a higher surface area, which improves the ability to harvest incident light and create more surface-active sites [55].…”

Chlorpyrifos (CP) is a globally used pesticide with acute toxicity. This work studied the photocatalytic degradation of CP using TiO2, ZnO nanoparticles, and nanocomposites of TiO2 and ZnO supported on SPIONs (SPION@SiO2@TiO2 and SPION@SiO2@ZnO). The nanocomposites were synthesized by multi-step incipient wetness impregnation. The effects of the initial pH, catalyst type, and dose were evaluated. The nanocomposites of SPION@SiO2@TiO2 and SPION@SiO2@ZnO showed higher CP photodegradation levels than free nanoparticles, reaching 95.6% and 82.3%, respectively, at pH 7. The findings indicate that iron oxide, as a support material for TiO2 and ZnO, extended absorption edges and delayed the electron–hole recombination of the nanocomposites, improving their photocatalytic efficiency. At the same time, these nanocomposites, especially SPION@SiO2@TiO2, showed efficient degradation of 3,5,6-trichloropyridinol (TCP), one of the final metabolites of CP. The stability and reuse of this nanocomposite were also evaluated, with 74.6% efficiency found after six cycles. Therefore, this nanomaterial represents an eco-friendly, reusable, and effective alternative for the degradation of chlorpyrifos in wastewater treatment.
