Abstract
Abstract Methylene blue (MB) is produced as a water pollutant in textile, paper and dye industries. At this work, N-Doped Graphene Quantum Dots (N-GQDs)/Titanium Dioxide(TiO 2 ) as new Nanocomposite is designed and used for removal of MB from water. N-GQDs is synthesized via hydrothermal procedure with citric acid and ethylene diamine as precursor. N-GQDs/TiO 2 is synthesized via simple stirring of N-GQDs and TiO 2 nanoparticles at 24 h. Synthesized N-GQDs and N-GQDs/TiO 2 is characterized with X-ray diffraction (XRD) analysis, Transmission Electron Microscopy (TEM), FT-IR, Scanning Electron Microscopy (SEM), Ultra violet (UV) and Photoluminescence (PL) spectroscopy. At the following, N-GQDs/TiO 2 is used as catalyst for photodegradation of MB. Results shows that N-GQDs have excellent effect on photocatalytic behavior of TiO 2 as common catalyst for photodegradation. By introducing of N-GQDs to TiO 2 nanoparticles, photodegradation efficiency of TiO 2 toward MB under UV light is increased from 40% to 85%.
