Abstract
AbstractNovel N‐doped Bi3O4Br/(BiO)2CO3 ultrathin nanojunctions have been prepared. Alkalization dehalogenation was performed to form Bi3O4Br, surfactant was employed to control the ultrathin thickness, and few‐layers of C3N4 as a sacrificial agent were used to build the N‐doped (BiO)2CO3. The photocatalytic behavior of the achieved N‐doped Bi3O4Br/(BiO)2CO3 ultrathin nanojunctions was evaluated through the degradation of antibiotic agent ciprofloxacin, tetracycline hydrochloride, and endocrine disrupting chemical bisphenol A as well as typical dye rhodamine B under visible light irradiation. The matched energy band structure between Bi3O4Br and (BiO)2CO3 could endow the highly efficient interfacial charge separation, thus leading to excellent nonselective photocatalytic behavior. The structure design in this system will open new windows for the reasonable design of other photocatalysts.
