Shape Evolution of Layer-Structured Bismuth Oxychloride Nanostructures via Low-Temperature Chemical Vapor Transport

Bismuth oxychloride (BiOCl) is a wide bandgap semiconductor used in cosmetics, pharmaceuticals, battery cathode, photocatalysis, and photoelectrochemical devices. We report here a facile low-temperature vapor-phase synthesis route for the direct grown of single crystalline BiOCl nanostructures on various substrates. We achieved control of a variety of morphologies including nanobelts, nanowires, nanoflowers, nanoflakes, and platelets.
