摘要
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。
A simple method was used to synthesize the silver nanoparticles, of which the multifunction was analyzed for using as surface enhanced Raman scattering （SERS） sub- strate, adsorbent, and photocatalyst. We investigated the UV light-assisted photocatalytic degradation of rhodamine 6G （R6G） on Ag nanoparticles monitored by UV-visible and SERS spectroscopies. The results indicated that R6G was degraded effectively. This study endows a new value of the SERS technique, which can be used as a new detection method for monitoring the photocatalytic processes.
