Overall, the XRD analysis confirms the successful synthesis of the doped photocatalysts, highlighting the dominant anatase phase and the presence of cerium oxide while indicating that silver and boron are either present in insufficient quantities or in forms that do not contribute to the diffraction pattern. These findings are essential for understanding the structural properties and potential photocatalytic performance of the synthesized materials. The XRD spectra of two doped photocatalysts are shown in below fig .
