The selected area electron diffraction
(SAED) pattern acquired from an individual BiOCl nanoplate
(Figure 5d) shows a regular and clear square diffraction spot
array with lattice spacings matching those of (113) and (012)
planes, demonstrating the existence of the BiOCl tetragonal
structure, which, in turn, is in agreement with the XRD results.
