摘要：Fe3O4 magnetic nanoparticles and Ag nanoparticles reduced by reductant were incorporated on ordered mesoporous carbon to form magnetic ordered mesoporous carbon composites incorporating Ag nanoparticles (magnetic OMC-Ag). The prepared magnetic OMC-Ag as a surface-enhanced Raman scattering (SERS) substrate not only exhibited a clearly enhanced effect but also showed enrichment ability for the detection of 4-nitrothiphenol. Ag nanoparticles-incorporated magnetic carbon composites as SERS substrate displayed Raman enhancement phenomenon for the detection of 4-nitrothiphenol and showed high stability.
