| Summary: | This study presents a straightforward, cost-effective method for synthesizing Tin Sulfide (SnS2) nanoparticles using magnetic stirring. The prepared SnS2 was analyzed using XRD, FESEM, EDAX, UV–Vis, FTIR, XPS, HRTEM, and SAED analysis. The photodegradation of Methyl Violet (MV) dye achieved a 93.8 % decolourization rate within 120 min, following first-order kinetic reaction rates. The half-life (t1/2) was determined to be 31.18 min, and the stability of the photocatalyst was evaluated under different pH conditions. Cyclic Voltammetry (CV) studies were performed using a carbon paste electrode in 2 M KOH, revealing a low electrochemical value and proton diffusion coefficient for SnS2, indicating good redox behaviour with a Csp of approximately 158 F/g. The electrochemical sensing of urea demonstrated excellent performance with the SnS2 electrode. Additionally, the sensor's pH response was investigated under three different pH conditions, showing remarkable urea sensing capabilities influenced by pH and electrolyte environment. |
