The XRD results for these photocatalysts would show distinct peaks corresponding to the anatase and rutile phases of Titanium dioxide, with shifts in peak positions and changes in peak intensities indicating the effects of doping. The peak broadening observed in the XRD patterns can be analyzed using Scherrer's equation to estimate the crystallite sizes, which, when combined with the lattice constants, provide a comprehensive understanding of the structural modifications induced by doping.
