Fibrous SiO2-TiO2 (FST) is one of the most promising materials for advancing photoelectrochemical water-splitting technology due to its cost-effectiveness and environmental friendliness. However, FST faces intrinsic limitations, including low conductivity wide bandgap. In this study, significant progress was made in modifying overcome some these limitations. This work involved synthesizing a new photoanode Ag-doped utilizing microemulsion process. The characterized using XRD, FTIR, UV–Vis, DRS, N2 adsorption–desorption, FESEM, TEM, XPS. results confirmed formation continuous concentric lamellar structure with large surface area. addition Ag species into matrix caused interactions that reduced exhibited an impressive photocurrent density 13.98 mA/cm2 at 1.2 V (vs. RHE). notably higher than photoanodes, which 11.65 Furthermore, conduction band positioned closer reduction potential hydrogen compared FST, SiO2, TiO2, facilitating rapid charge transfer enabling spontaneous generation H2. fabrication provides valuable insights development high-performance photoanodes PEC water splitting.
