| 摘 要： | 通过置换反应在金属铝表面制备了表面没有任何保护剂且具有红外增强作用的钴岛膜,用SEM、XRD和表面增强红外光谱对其形貌和性质进行表征。 结果表明,铝片上沉积出的钴呈岛状结构,钴岛膜由二次钴粒子和一次钴粒子通过密堆积的方式构成;首次发现具有这种特殊结构的钴对吸附于其表面的有机分子的红外吸收光谱有较大的增强作用,用此钴岛膜对1 mmol/L的对巯基苯甲酸的红外光谱研究时得到很好的红外增强信号,使得表面增强红外光谱可以用于痕量分析、检测。

| Abstract: | Protective agent free cobalt-island film with infrared enhancement effect was prepared on aluminum metal surface by replacement reaction. Its morphology and characteristics were investigated by using SEM, XRD and IR. Cobalt deposited on aluminum surface emerged as an island structure. Cobalt island films were formed by a large number of secondary cobalt particles and a small amount of cobalt particles through a close packing pattern. Cobalt's unique structure enables a significant enhancement effect on infrared absorption spectrum of organic molecules which are adsorbed on the surface of silver particles. The infrared spectroscopy of 1 mmol/L para-mercaptobenzoic acid has been greatly enhanced on the cobalt-island film. Therefore, the surface-enhanced infrared spectroscopy can be used for trace analysis and testing. |
