As can be seen, the two spectra are nearly identical, confirming the correctness of the synthesis procedure. The peaks observed at = 24.5 and 47° indicate the anatase phase, while the slight rise immediately following this at about 29° suggests the presence of the cerium oxide (111) phase. Since silver ion is relatively large compared to titanium and cerium, besides being present in meagre amounts, the XRD spectra do not show the presence of silver. Boron is also not indicated.
