Incubator‐shaker method was used as a rapid technique to fabricate an efficient surface enhanced Raman scattering (SERS) substrate by combination of zero valent nanostructures and carbon fiber, which shows dramatic Raman enhancement of nitroaromatic molecule. The fabricated Ag nanoparticle on carbon‐fiber substrate (Ag–C) was used as an efficient SERS substrate to detect the adsorbed 2, 4‐dinitrotoluene molecules with a detection limit of 50 ppm. In advent, our developed SERS substrates could have great potential in detecting other nitro‐aromatic based‐explosive materials, such as 2, 4, 6‐trinitrotoluene molecules.
