Abstract

A facile and fast microwave irradiation method has been developed to synthesize uniform well-defined 3D flowerlike BiOBr nanostructures through a self-assembly process. Cetyltrimethylammonium bromide (CTAB), which acts as both the bromide source and soft template, plays a critical role in the formation of 3D flowerlike BiOBr nanostructures. Different flowerlike BiOBr nanostructures could be obtained by varying the CTAB concentration. A possible formation process is discussed. The as-prepared flowerlike BiOBr nanostructures possessed a large surface area and exhibited an excellent removal capacity and fast adsorption rate for CrVI ions in a wide pH range.
