However, the XRD pattern is an average of the entire reactor bed, so a gradual peak shift can also indicate that the . We hypothesize that the experimentally observed XRD peak shift toward lower angles may be caused by: 1) Cd 2+ accumulation at the interstitial lattice sites, which may release lattice strain leading to an increase in Pb I Pb angles; or 2) change in the iodide-to-bromide ratio, with a higher iodide concentration leading to lattice expansion. The main peaks are observed at 4°, 15.
