Fig shows HRTEM images of the as synthesized BiOCl

Fig. 5b and c reveals the highly crystalline nature of the pure BiOCl nanosheets and show a partial enlarged HRTEM of pure BiOCl. The clear lattice fringes with an interplanar lattice spacing of 0.27 nm correspond to the (1 1 0) plane in good agreement with the XRD results. Furthermore, TEM and XRD results also confirm that the top surface of prepared BiOCl nanosheet units are identified as 0 0 1 facets and the four lateral surfaces are 1 1 0 facets.
