摘要

Present research demonstrated polysulphide electrolytes’ photocatalytic stability with Stannic Oxide (SnO2) under visible light irradiation. There are mainly two parameters studied in this work such as the amount of photocatalyst and concentration of polysulphide electrolyte. The optical properties of SnO₂ before and after irradiation were investigated using UV–Visible spectroscopy, the structural characteristics were examined using X-ray diffraction (XRD), and the morphological features were analyzed using a scanning electron microscope (SEM) and Elemental analysis with EDS. The concentration and mineralization of polysulphide electrolytes were measured with a UV–Visible spectrophotometer. The photodegradation of polysulphide electrolytes was observed by 25 mg, 50 mg, and 75 mg of SnO2 in 0.1 M of polysulphide electrolyte. The interaction between SnO2 and polysulphide species is systematically analyzed, providing critical insights into the effects of SnO2 as a photoanode. The study aims to understand the mechanisms and interactions at the SnO2-polysulphide electrolyte interface, providing crucial insights for designing more stable and efficient energy conversion. The findings presented here contribute to the broader understanding of how SnO2 influences the stability of polysulphide electrolytes, providing a foundation for optimizing the performance of Solar cells.
