Abstract	Novel NiS/CdS heterostructures with enhanced visible-light photocatalytic activity were successfully prepared via a facile two-step hydrothermal process. The synthesized materials were characterized using X-ray diffraction, high-resolution transmission electron microscopy and UV-Vis diffuse reflectance spectroscopy. The photocatalytic activity was investigated by the degradation of quinoline under visible light irradiation. The experimental results reveal that the CdS samples are hexagonal phases with high crystallinity and purity. As-prepared NiS/CdS heterostructures exhibit a higher photocatalytic activity than pure CdS or NiS. The improvement was ascribed to the formation of p-n NiS/CdS heterojunction, which can promote the light absorption capability of photocatalyst and separation of excited electron-hole pairs.
