| 摘 要： | 采用两步水热法制备了WS2/MgAl-LDH(水滑石)复合材料,通过X-射线衍射仪、傅立叶变换红外光谱仪、场发射扫描电子显微镜、透射电子显微镜和X-射线光电子能谱仪等测试分析,表明在MgAl-LDH层间原位合成了WS2纳米粒子。将该复合材料作为催化剂来降解150 mg/L,pH值为3的甲基橙溶液,其结果是:在模拟可见光条件下辐照75 min,该甲基橙溶液的降解率超过80%,且循环性能优异。由此表明,WS2/MgAl-LDH复合材料是一种极具应用潜力的光催化剂。

| Abstract: | The WS2/MgAl-LDH composite was prepared by a two-step hydrothermal method. The analysis of X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscope, transmission electron microscope and X-ray photoelectron spectroscopy show that the WS2 nanoparticles are synthesized in situ between layers of MgAl-LDH. The composite was used as a catalyst to degrade 150 mg·L-1 methyl orange solution with pH value of 3.The results show that the degradation rate of methyl orange solution exceeds 80% under simulated visible light irradiation for 75 min, and the cycling performance is excellent. Therefore, WS2/MgAl-LDH composite is considered a promising photocatalyst. |
