Photocatalytic degradation of norfloxacin antibiotics on ZnCdS/g-CN composites in water.

g-CN/ZnCdS composites were synthesized by a simple hydrothermal method. The composites were characterized by X-ray diffraction, UV-vis diffuse reflectance spectroscopy, infrared spectroscopy, and electron micro-projective microscopy. According to the performance of ZnCdS for the photocatalytic degradation of norfloxacin under visible light in water, the best stoichiometric number of x was 0.
