【摘要】 表面等离激元催化反应为表面过程的拓展提供了一条新的途径，但在单一贵金属表面的反应效率往往较低，因此发展符合纳米结构已经成为该领域的研究热点。通过合成八面体的氧化亚铜（Cu₂O）,并引入高均匀性和高SERS活性的金纳米粒子单层膜（Au MLF）,将两者完全结合，构建了Cu₂O-Au复合异质结SERS基底。以对硝基苯硫酚（PNTP）为探针，通过表面增强拉曼光谱（SERS）研究了Cu₂O-Au表面等离激元驱动的偶联反应。结果表明，Cu₂O与Au MLF的复合，其SERS性能及催化活性都得到了较大的提升，为发展高性能的新型复合纳米结构提供了实验基础。更多还原

【Abstract】 Surface plasmon resonance（SPR） catalysis reactions provide a novel approach for the extension of relevant surface processes. However, the surface reaction efficiency was quite poor on a single noble metal surface. Thus, the development of composite nanostructures was highly desired. Herein, the Cu₂O-Au composite heterojunction was fabricated by the synthesis of copper oxide（Cu₂O） and the attachment of gold nanoparticle monolayers film（Au MLF） with high uniformity and high SERS activity. By using p-nitrothiophenol（PNTP） as a probe, surface enhanced Raman spectroscopy（SERS） was developed as the sensitive tool for monitoring the SPR catalysis reaction. The results demonstrated that the SERS performance and catalytic activity of Cu₂O and Au MLF are significantly improved. It would provide an experimental basis for the development of high-performance novel composite nanostructures.更多还原
