Visible irradiation induced photodegradation by NbC/C nanocomposite derived from smoked cigarette litter (filters)

摘要

In a view to the treatment required to degrade organic effluents and also waste utilization, a non-treditional photocatalyst (NbC/C nanocomposite) has been synthesized by using Nb2O5 and cigarette litter (filter) at relatively low temperature 800 degrees C. With the help of XRD diffraction technique, the synthesis parameters have been optimized to get NbC/C nanocomposite and studied their morphology by transmission electron microscopy (TEM). The synthesized nanocomposite NbC/C was used to study the photocatalytic degradation of methylene blue (MB) dye under visible light illumination. Further, the effect of concentration of dye and photocatalyst has been studied under same conditions. With the help of BET, UV-visible absorbance, XPS, mass spectrometry and total organic carbon analysis, degradation mechanism has been established for the optimized nanocomposite sample.
