Abstract: To improve the performance of surface-enhanced Raman scattering (SERS), Ag and Au nanoparticles (NPs) were loaded on the surface of ordered mesoporous carbon (OMC) using an ultrasonic technique. The microstructure was characterized through TEM, SEM and XRD techniques. And R6G were used as probe molecules to evaluate the SERS performance of OMC/Ag@Au NPs composite. The pore size and surface area of OMC/Ag@Au NPs composite were 5.9 nm and 426.1 m2·g-1, which exhibits great ability of enrichment for organic molecules. The detection limit of R6G is determined to be as low as 10-8 mol/L. Furthermore, the RSD of the peak intensity at 613 cm-1 is 3.7%, and it remained high SERS activity stored over 45 days under ambient condition. Through a simple and low-cost ultrasonic technique, we prepared OMC/Ag@Au NPs composite which exhibits high SERS activity, reproducibility and stability. The excellent SERS activity mainly stems from two distinct mechanisms, electromagnetic enhancement from surface plasmon resonance (SPR) of Ag NPs and Au NPs as well as chemical enhancement from absorption effect of OMC, indicating a great potential in detecting organic pollutants.
