In the present study, we report systematic investigation of effect chemical oxidation on structure single-walled carbon nanotubes (SWNTs) by using different oxidants. The procedure was characterized infrared spectroscopy and transmission electron microscopy (TEM). SWNTs were produced vapor deposition (CVD) oxidized with three kinds oxidants: (1) nitric acid (2.6 M), (2) a mixture concentrated sulfuric (98 wt %) (16 M) (v/v = 3/1) (3) KMnO4. results reveal that functional groups can be...
Abstract Surface-enhanced Raman spectroscopy (SERS) represents a very powerful tool for the identification of molecular species, but unfortunately it has been essentially restricted to noble metal supports (Au, Ag and Cu). While application semiconductor materials as SERS substrate would enormously widen range uses this technique, detection sensitivity much inferior achievable enhancement was rather limited, thereby greatly limiting practical applications. Here we report employment...
