Abstract
In this study, TiO2-graphene oxide composites with different weight ratio of Titanium (ІV) butoxide /Graphene Oxide were synthesized by sol-gel method. The products were characterized by X‐ray diffraction method and UV-Vis spectrophotometer. The TiO2-graphene oxide composites possessed a large adsorption capacity for methylene blue and extended light absorption range in comparison to the pure TiO2. Evaluation of non-linear adsorption isotherm models including Langmuir and Freundlich suggests that adsorption data can be well described by Freundlich isotherm models. Adsorption of methylene blue on the surface of composite is chemisorption.
