Abstract |
Abstract In this study, we report on successful attempt towards the synthesis of sulfur
self-doped g-C3N4 by directly heating thiourea in air. The synthesized materials were characterized
using UV-vis spectral technique, FT-IR, XRD and TEM analysis. Further, the obtained
material shows an excellent detection of carcinogenic TNP(Tri nitro phenol) in the
presence of 10-fold excess of various other common interferences. The strong inner filter
effect and molecular interactions(electrostatic, ¥ð-¥ð, and hydrogen bonding interactions)
between TNP and the S-g-C3N4 Nano sheets led to the fluorescence quenching of the Sg-
C3N4 Nano sheets with an excellent selectivity and sensitivity towards TNP compared to
that of other nitro aromatics under optimal conditions and the detection limit calculated
was found to be 6.324 nM for TNP. The synthesized nanocomposite provides a promising
platform for the development of sensors with improved reproducibility and stability for
ultra-sensitive and selective sensing of TNP. |
