Enhanced Visible Light Photocatalytic Activity of Lead Selenide/Graphene/Titanium Dioxide Nanocomposite Synthesized via Ultra-Sonication Technique

摘要

In this study, we investigated the photo-degradation efficiency of PbSe-G-TiO2 ternary nanocomposite under visible light irritation using rhodamine B as standard dye, A nanocomposite was synthesized by ultra-sonication technique and characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopic analysis and UV-visible absorbance spectra analysis. The results indicate that PbSe-G-TiO2 ternary nanocompsite has excellent stability and good photodegradation efficiency than PbSe-G and TiO2-G nanocomposite which is approximately 92.5 % of rhodamine B degradation after visible light irradiation for 180 min.
