Abstract:

In this communication, we report on the preparation of Ag nanoparticle-decorated 2,4,6-tris (2-pyridyl)-1,3,5-triazine nanobelts (AgNP-TPTNBs) by mixing a AgNO3 aqueous solution and pre-formed TPTNBs with the aid of sodium hydroxide in the absence of any external reducing agent. The formation mechanism of AgNP-TPTNBs is discussed from the seed-mediated growth and considering the reduction potential of triazine and Ag(I) ions under alkaline conditions. It is found that the resultant AgNP-TPTNBs show great potential of Surface-enhanced Raman scattering (SERS) technique with high sensitivity up to 1.0x10-10 M by using p-aminothiophenol (p-ATP) as the model Raman probe.
