Plasmon-mediated chemical reaction (PMCR) is a highly attractive field of research. Here we report in situ surface-enhanced Raman spectroscopic (SERS) monitoring of plasmonic-mediated SS bond-forming reaction. The reaction is thought to be a self-coupling reaction proceeding by photoinduced aromatic SC bond arylation. Surprisingly, the SC arylation and SS coupling are found to be occurred on both partially oxidized silver and silver nanoparticles. The results demonstrated that silver oxide or hydroxide and small molecule donor sacrifice agent played a crucial role in the reaction. This work facilitates the in-situ manipulation and characterization of the active silver electrode interface in conjunction with electrochemistry, and also establishes a promising new guideline for surface plasmon resonance photocatalytic reactions on metal nanostructures with high efficiency.
等离子体介导的化学反应（PMCR）是一个极具吸引力的研究领域。在此，我们报告了对等离子体介导的SS键形成反应的原位表面增强拉曼光谱（SERS）监测。该反应被认为是通过光诱导的芳香族SC键芳基化进行的自偶联反应。令人惊讶的是，发现SC芳基化和SS偶联在部分氧化的银和银纳米颗粒上均会发生。结果表明，氧化银或氢氧化银以及小分子供体牺牲剂在该反应中起着关键作用。这项工作有助于结合电化学对活性银电极界面进行原位操作和表征，同时也为金属纳米结构上的表面等离子体共振光催化反应高效地建立了一条有前景的新指导方针。
