英文摘要Porous graphitic carbon nitride (Pg-C3N4) nanosheets have been prepared via thermal decomposition, and then novel 2D Pg-C3N4/BiOBr hybrid is designed by a facile hydrothermal process. The as-prepared Pg-C3N4/BiOBr hybrids are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-Vis diffuse reflectance spectroscopy (DRS). The results show that BiOBr tightly composited on the surface of Pg-C3N4. Enhanced electron and hole separation efficiency is confirmed by photoluminescence (PL) spectroscopy measurements and the photoelectrochemical evaluation. The photoactivity performance of Pg-C3N4/BiOBr is tested under visible-light irradiation, the result shows that coupling semiconductor of Pg-C3N4/BiOBr apparently enhances the photocatalytic activity. An optimal Pg-C3N4 content has been determined to be 20 wt%, corresponding to apparent pseudo-first-order rate constant k(app) of 0.088 min(-1), which is 3.7 times, 4.2 times and 7.3 times as high as that of Pg-C3N4, BiOBr and common g-C3N4, respectively. Furthermore, photocatalytic stability and mechanism of enhanced photocatalytic process are also investigated. (C) 2017 Elsevier B.V. All rights reserved.
