- Abstract
g-CN/BiOX (X = Cl, Br, I) composite photocatalysts have been prepared by means of a facile immersion-hydrolysis method. The microstructural and morphological characteristics of the as-prepared composite photocatalysts were investigated by means of X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy, and Fourier-transform infrared spectroscopy. The photodegradation performance of both g-CN/BiOCl and g-CN/BiOBr composites was superior to that of pure g-CN or the corresponding bismuth oxyhalides, possibly because of efficient separation of photogenerated carriers at the interface between g-CN and BiOX (X = Cl, Br). The photostability of as-prepared g-CN/BiOX (X = Cl, Br) composites was also investigated.
