“…A vast array of synthetic procedures have been developed, such as template‐aided synthesis , hydro/solvothermal preparation , sonochemical route , and ionothermal synthesis , to construct two dimensional (2D) BiOCl nanostructures of nanobelts , nanofibers , nanoplates , nanosheets , and nanoflakes . Especially, nanoplates are extensively studied not only for their unique optical and catalytic properties, but also for the applicable use to further fabricate 3D hierarchical nanoflower‐like or nanosphere‐like structures .…”
