采用溅射银提供的 SERS 来检测 SOFC 电极上的痕量化学物质。焦化镍表面、CeO(2) 涂层和阴极材料（LSM 和 LSCF）的拉曼信号显着增强，检测阈值降低，这表明了一种探测电极降解和表面催化机制的可行方法。
SERS provided by sputtered silver was employed to detect trace amounts of chemical species on SOFC electrodes. Considerable enhancement of Raman signal and lowered detection threshold were shown for coked nickel surfaces, CeO(2) coatings, and cathode materials (LSM and LSCF), suggesting a viable approach to probing electrode degradation and surface catalytic mechanism.
