“…However, the construction of a specific charge transfer pathway between the carbon substrate and target explosive molecules has not been sufficiently considered in the current research. Especially, the stability and reproducibility of carbon-based materials − are also their major advantages as SERS substrates. Jiang et al developed a simple method for preparing an efficient and stable SERS substrate by combining Ag nanoparticles (NPs) and microscale sheeted graphitic carbon nitride (g-C 3 N 4 ), and the EF of crystal violet (CV) is 4.6 × 10 8 .…”

Selective surface-enhanced Raman scattering (SERS) detection of target explosives with good reproducibility is very important for monitoring soldiers’ health and ecological environment. Here, the specific charge transfer pathway was constructed between a stable nanodiamond-multilayer graphene (MGD) film substrate and the target explosives. Two-step wet chemical oxidation methods of H2O2 (30%) and HNO3 (65%) solutions were used to regulate the terminal structure of MGD films. The experimental results showed that the hydroxyl (−OH) functional groups are successfully modified on the surface of MGD thin films, and the MGD–OH substrates having good selectivity for 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) explosive in mixed solutions of the TATB, 2,2-dinitroethene-1,1-diamine, 2,4,6-trinitrotoluene, and 1,3,5-trinitroperhydro-1,3,5-triazine explosives compared with MGD substrates were demonstrated. Finally, first-principles density functional theory simulations revealed that the SERS enhancement of the MGD–OH substrate is mainly attributed to the transferred electrons between the –NO2 groups of TATB and the −OH groups of the MGD–OH substrate.
