中文摘要：
利用简单的水热法在ZnO纳米棒表面合成CdS纳米粒子。用扫描电镜（SEM）和X射线衍射（XRD）对CdS/ZnO异质结构进行表征。实验结果表明,在生长CdS的过程中ZnO被逐渐地腐蚀。选择CdS/ZnO纳米复合材料作为光催化剂在紫外光和绿光照射的条件下降解甲基橙（MO）。CdS/ZnO纳米复合材料纳米棒作为光催化剂降解甲基橙的光催化活性有明显的提高。
英文摘要：
CdS nanoparticles were synthesized on ZnO nanorods by a sample hydrothermal method.The as-grown ZnO/CdS heterostructures were characterized by scanning electron microscopy（SEM）,X-ray diffraction（XRD）.It is shown that ZnO nanonods could be gradually corroded with the growth process of CdS.We selected ZnO-CdS nano-composites as a configuration to decompose methyl orange（MO） under ultraviolet and green light irradiation.Compared with ZnO nanorods,the absorption spectrum of CdS/ZnO nano-composites could be extended from ultraviolet to visible light,then compared with ZnO nanorods the photocatalytic activity of the nano-composites was obvious enhanced.
