Surface Enhanced Raman Spectroscopy (SERS) technology can be used to detect trace amounts of polycyclic aromatic hydrocarbons (PAHs) in the environment due to its convenience,sensitivity and fingerprint characteristics.A new type of SERS substrates,composed of hierarchical thiol-modified silver nanowire-graphene-gold nanosphere,is able to induce rich electromagnetic field enhanced area and synergistically selectively adsorb PAHs in the environment through π-π stacking interaction and hydrophobic interaction,achieving the amplification of Raman signal of PAHs.The minimum detection concentration of pyrene,benzopyrene,anthracene,and phenanthrene by this substrate was 10-6 mol/L,and the correlation coefficients of the characteristic peak intensity and the logarithm of the concentration were all larger than 0.98,as well as the substrates had good uniformity.The SERS substrates can quickly and accurately realize the qualitative and quantitative detection of polycyclic aromatic hydrocarbons,which could provide technical support for improving the pollution situation of polycyclic aromatic hydrocarbons in the chemical production and the environment.
