Scanning Electron Microscopy (SEM) analysis is an essential tool for understanding the surface morphology and microstructural features of photocatalysts. Fig. showcases the SEM images of the three tri-doped photocatalysts (B1Ce1Ag0.1TiO₂, B1Ce1Ag0.06TiO₂, and B1Ce0.1Ag0.06TiO₂) employed in this study. These images provide valuable insights into the physical structure of the catalysts, which can directly influence their photocatalytic performance.
