花球状MoS_2的制备及光催化性能研究

Preparation and photocatalytic properties of petal-shaped MoS_2

采用溶剂热法合成了花球状MoS_2材料,利用X射线衍射(XRD)、扫描电子显微镜(SEM)对样品的微观结构和表面形貌进行了表征,利用紫外-可见光分度计(UV-vis)对花球状MoS_2在可见光下光催化降解罗丹明B溶液的活性进行了研究,结果表明花球状MoS_2具有较好的吸附效果和光催化活性.

Petal-shaped MoS2 were synthesized by the hydrothermal method. The morphology and microstructure of samples were characterized by X-ray diffraction（ XRD） and scanning electron microscopy（ SEM）. The activity of petal-shaped spherical MoS2 in the degradation of Rhodamine B solution under visible light was studied by UV-vis absorption. The results showed that the petal-shaped MoS2 had the good adsorption ability and photocatalytic activity.
