摘要
本文提出基于无标记SRES检测壳层隔绝Au核负载Pt纳米粒子对甲酸催化反应方法。将催化反应和SERS活性整合在单粒子双功能的3D结构上,即将卫星结构的Pt纳米粒子自组装在壳层隔绝的Au核上,这样的结构还能消除光催化副反应的影响。
Label-free in situ surface-enhanced Raman scattering(SERS) monitoring of HCOOH reactions catalyzed by small Pt nanoparticles supported on shell-isolated Au core is presented. Catalytic and SERS activities are integrated into a single bifunctional 3D superstructure comprising small Pt satellites self-assembled onto a large shell-isolated gold core, which eliminates photocatalytic side reactions.
