| Abstract: | Our current research described in this manuscript explored the facile synthesis of Keggin-type Silicotungstic acid (STA)-modified TiO2 nanocomposites and their multifunction properties. The nanocomposites were synthesized using a simple and efficient sonication method, resulting in well-dispersed STA molecules in the TiO2 matrix as evidenced by SEM coupled with EDX analysis. Doping TiO2 with STA significantly enhanced its electrical properties compared to bare TiO2, demonstrating a synergistic effect between STA and TiO2. Additionally, the band gap value was notably reduced (from 2.96 to 2.84 eV) with increasing STA concentration, confirming the formation of the composites. The photocatalytic degradation performance of the composites was evaluated using methylene blue (MB) dye as a pollutant molecule by investigating various parameters such as catalyst loading, pH of the solutions and demineralization. Furthermore, the nanocomposites were tested for their potential biocompatibility and effect on seed germination. The results demonstrated that the composites positively influenced wheat seeds' germination rate and early growth, making them promising candidates for agricultural applications.
