摘要：

The photocatalytic properties of CdS semiconductors were investigated for the photoreduction of 4-Nitrophenol with Na2SO3 under blue light irradiation. The materials were synthesized by co-precipitation method in ethylenediamine-water solution and their structural and optical properties were characterized by X-ray diffraction, UV-vis spectroscopy and nitrogen physisorption. The CdS semiconductor prepared at higher EN contents (90 vol.%) presented the highest photocatalytic activity for the reduction of 4-Nitrophenol to 4-Aminophenol. Their photo-efficiency enhancement is attributed to the quantum confinement effect caused by the small particle size (similar to 15 nm). (C) 2013 Elsevier B.V. All rights reserved.
