摘要 将硫化钼(MoS2)与氧化锌(ZnO)纳米棒结合,制备了MoS2/ZnO压电近红外光催化复合材料。采用X-射线粉末衍射(XRD)、扫描电镜(SEM)、透射电镜(TEM)、紫外-可见-近红外漫反射光谱(UV-VIS-INF-DRS)、 固体荧光等方法对MoS2/ZnO样品进行了表征。结果表明,MoS2/ZnO生成了异质结。以0.1 g MoS2/ZnO材料作为压电近红外光催化剂,在压电条件下降解pH=10浓度为100.0 mg/L的氨氮溶液,当在搅拌(250 r/min)条件下,用850 nm波长的近红外光照射6 h时,氨氮的降解率为90.97%;而相同条件下,无压电效应时近红外光催化降解氨氮的效率仅为65.16%,表明压电效应增强了氨氮的降解。其原因是ZnO压电构建的内建电场增强了MoS2光生电子与空穴的分离效率。动力学研究表明,MoS2/ZnO降解氨氮的反应遵循一级反应动力学规律,其表观反应速率常数的平均值为0.298 7 h-1。该研究结果对利用太阳能和水波能降解氨氮具有潜在的应用价值。

Abstract: AMoS2/ZnO piezo-photocatalyst in response to near-infrared irradiation was prepared using hydrothermal reaction. MoS2/ZnO was characte-rized with X-ray powder diffraction(XRD), scanning electron microscopy(SEM), transmission electron microscopy(TEM), ultraviolet-visible-near-infrared diffuse reflectance spectroscopy(UV-VIS-INF-DRS), solid fluoroscopy. The facts showed that the heterojunction was formed between MoS2 and ZnO. MoS2/ZnO of 0.10 g was used as the photocatalyst to degrade 100.0 mg/L ammonia-nitrogen with pH 10.0 under stirring (250 r/min) and upon 850 nm near-infrared irradiation for 6 h, resulting in the degradation ratio of 90.97%, whereas the degradation ratio of ammonia-N was only 65.16% under similar conditions except for stirring. It indicated that piezo-effect enhanced the degradation of ammonia-N, which is ascribed to the enhanced separation of photo-generated electrons and holes in MoS2 upon near-infrared irradiation. The kinetics showed the degradation reaction of ammonia follows the first-order reaction law, the average of the apparent kinetics constant is equal to 0.298 7 h-1. The research showed solar irradiation and water waves could be used to remove ammonia in wastewaters.
