The Editors retract this article due to duplication and alteration of the X-ray diffraction (XRD) patterns in Figure 1 and the energy-dispersive X-ray (EDX) spectroscopy plots in Figure 4. The XRD patterns in Figure 1 appear to be identical, although they are presented as different samples. Additionally, the EDX spectrum in Figure 4 shows a peak that seems to have been truncated, and the label may have been removed. These concerns are significant enough to cast doubts on the main findings of the work.
