用一种简单的方法制备银纳米粒子,研究了此纳米粒子作为SERS基底、吸附剂和光催化剂的多功能性。在光照条件下研究其对染料分子的光催化性能,用紫外光谱和表面增强拉曼光谱对整个光催化过程进行动态跟踪检测,实验结果表明染料分子光照条件下确实被催化降解了。本实验不仅合成了多功能的基底材料,还赋予了表面增强拉曼光谱新的应用价值,为光催化实验提供了新的动态跟踪检测方法。
Silver nanoparticles were prepared by a simple method and the versatility of the nanoparticles as SERS substrates, adsorbents and photocatalysts was investigated. The photocatalytic properties of the dye molecules were studied under light irradiation conditions. The UV-Vis spectrum and surface-enhanced Raman spectroscopy were used to detect the photocatalytic activity. The experimental results showed that the dye molecules were indeed degraded under light irradiation. In this experiment, we not only synthesized multifunctional substrate materials, but also provided new application value of surface enhanced Raman spectroscopy, which provided a new dynamic tracking detection method for photocatalytic experiments.
