| 摘 要： | 利用简易、绿色、一锅煮的水热法合成了花状氧化锌/银复合纳米材料。然后利用各种光谱和显微技术对复合物进行了表征，并讨论了其表面增强拉曼（SERS）性能和光催化性能。结果表明氢氧化钠的量对于这种复合纳米材料的形貌和性能具有重要的调节作用。和其他形貌的氧化锌/银复合纳米材料相比较，花状氧化锌/银复合纳米材料具有最佳的光催化性能。同时进一步以花状氧化锌/银复合纳米材料作为SERS基底研究其表面增强拉曼性能，结果表明这种复合材料同时具有很好的表面增强拉曼性能。光催化和表面增强拉曼结果表明这种花状氧化锌/银复合纳米材料有望在有机物检测中作为一种具有很好的可循环性的新表面增强拉曼基底材料。

| Abstract: | Multifunctional flower-like ZnO/Ag nanocomposites were prepared by a facile, green and one-pot hydrothermal method. The as-prepared samples were investigated by using various spectroscopic and microscopic techniques in detail. The surface-enhanced Raman scattering (SERS) performance and photocatalytic activity of the nanocomposites were also investigated. The results show that the amounts of NaOH play a key role in controlling the morphologies and properties of these nanocomposites. The flower-like ZnO/Ag nanocomposites exhibit the best photocatalytic performance for rhodamine 6G (R6G). Meanwhile, the optimized nanocomposites (the flower-like ZnO/Ag nanocomposites) are then employed to study the SERS performance, which also show excellent SERS activity. The photodegradation and SERS results reveal that ZnO/Ag nanocomposites act as promising candidates for a new substrate and exhibit high recyclability in the detection of organic molecules. |
