Surface-enhanced Raman spectroscopy (SERS) technology, based on noble metal nanostructures as substrate, is a highly sensitive method for the detected substance. When the surface of noble metal with special nanostructure is irradiated by laser, the free electrons on the metal surface will be greatly oscillated. While the frequency of the incident light is close to that of the oscillation, the surface plasmon resonance (SPR) will occur around the noble metal nanostructures material, greatly enhancing the local electric field intensity of the metal surface. The intensity of incident light and the scattering light will be also multiplied. As a result, the Raman scattering signals of molecules adsorbed on the surface of noble metal nanostructures will be effectively enhanced. In this paper, the octahedral Au/Ag composite nanocages were prepared by using NaBH4 reduction-acid etching template method. The prepared octahedral Au/Ag composite nanocages are uniform in shape, with the size of about 600 nm, and there is no residual cuprous oxide template. The Au element is uniformly distributed on the Ag nanocages with the mass fraction about 16.8%. Compared with that of Ag nanocages, the UV-vis absorption peak of the Au/Ag composite nanocages is red-shifted. More importantly, the synergistical action of Au and Ag element endow the Au/Ag composite nanocages with ultra-high SERS sensitivity and reproducibility. The trace detection of R6G at an ultralow concentration of 5×10-14 mol/L can be attributed to the high electromagnetic field intensity generated by the surface plasmon resonance, which was certificated by the finite difference time domain (FDTD) simulation method. Besides, the addition of the Au element provided the Au/Ag composite nanocages with excellent oxidation resistance and chemical stability. The excellent SERS performance can be kept even after soaking in 1% H2O2 solution for 3 h. The octahedral Au/Ag composite nanocages are a promising SERS substrate with high sensitivity and stability.
