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。
Flower-shaped zinc oxide / silver composite nanomaterials were synthesized by simple, green, one-pot hydrothermal method. The complexes were characterized by various spectroscopic and microscopic techniques and their surface enhanced Raman (SERS) and photocatalytic properties were discussed. The results show that the amount of sodium hydroxide for this composite nanomaterials morphology and properties have an important regulatory role. Compared with other morphologies of zinc oxide / silver composite nanomaterials, flower-like zinc oxide / silver composite nanomaterials have the best photocatalytic activity. At the same time, the surface enhanced Raman properties of flower-like zinc oxide / silver nanocomposites were also studied as SERS substrates. The results show that the composites also have good surface-enhanced Raman properties. The photocatalytic and surface-enhanced Raman results show that the flower-like zinc oxide / silver composite nanomaterials are expected to be a new surface-enhanced Raman matrix material with good recyclability in organics detection.
