摘要

以显示表面等离子体共振（SPR）效应和光催化活性的催化体系 Au@CdS 为例，研究了金属-半导体双功能核壳纳米材料。讨论了所研究纳米材料光催化活性的一些机制。利用表面增强拉曼光谱（SERS）原位监测了 SPR 驱动的 4-硝基苯硫酚（pNTP）到 4,4′-二巯基偶氮苯（DMAB）的光催化二聚反应。通过监测探针分子的拉曼光谱变化，跟踪了 Au@CdS 中 "热 "电子的转移路径。纳米材料 Au@CdS 在光催化降解罗丹明 6G 方面表现出很高的催化活性。该 SPR 显示金属半导体纳米复合材料是一种极具前景的光催化和原位 SERS 探针。

In situ surface-enhanced Raman spectroscopy study of interfacial catalytic reaction of bifunctional metal nanoparticles

Metal-semiconductor bifunctional core-shell nanomaterials were studied using catalytic system Au@CdS as example that displayed surface plasmon resonance (SPR) effects and photocatalytic activity. Some mechanisms of photocatalytic activity of the studied nanomaterials were discussed. Surface-enhanced Raman spectroscopy (SERS) was used to monitor in situ the SPR-driven photocatalytic dimerization of 4-nitrothiophenol (pNTP) to 4,4′-dimercaptoazobenzene (DMAB). The transfer path of “hot” electrons in Au@CdS was tracked by monitoring Raman spectral changes of the probe molecule. Nanomaterials Au@CdS showed high catalytic activity in photocatalytic degradation of rhodamine 6G. The SPR-displaying metal-semiconductor nanocomposite was indicated to be an extremely promising photocatalytic and in-situ SERS probe.
