【摘要】 表面增强拉曼散射(SERS)是吸附在纳米材料表面分子的拉曼信号被极大增强的现象，而纳米材料由于其量子效应具有优异的催化功能。协同复合材料的催化与SERS活性，在原位-动态环境条件下，研究催化剂本身及其表面的分子转化催化过程，间接超灵敏检测小分子、重金属离子、生物分子等对于催化体系研究具有重要的意义。最近构筑了一系列SERS-催化集成体系，并利用SERS技术研究了其催化机制与应用。更多还原

【Abstract】 Surface enhanced Raman scattering（SERS） is a phenomenon that the Raman signals of molecules adsorbed on the surface of nanomaterials are greatly enhanced. Nanomaterials have an excellent catalytic function due to quantum effects. It is of great significance for the study of catalytic system to explore the catalytic materials itself and catalytic process of surface of catalytic materials under in-situ dynamic environmental conditions, and indirect ultra sensitive detection of small molecules, heavy metal ions and biomolecules. Recently, we have constructed a series of SERS catalytic integrated systems, and studied their catalytic mechanism and application by using SERS technology. We have constructed a series of composite nanomaterials, such as MnCo₂O₄/Au nanotubes, Au-NiFe（LDH）/rGO, Ag/GQDs, Ag@CDs etc., to realize indirect high sensitive sensing of H₂O₂, F^-, Hg²⁺, organic mercury, etc., to explore the contribution of photocatalysis and photothermal effect to plasma mediated reaction under UV/vis/NIR irradiation, and to accurately detect the intracellular production of ROS and concentration of H₂O₂ at the subcellular level.更多还原
