The degradation of environmental pollutants is a major concern in materials chemistry. This study aims to enhance the photocatalytic efficiency of titanium dioxide (TiO2) nanocomposites by integrating them with graphene oxide. The research employs a sol-gel synthesis method to prepare the TiO2-graphene oxide composites. The structure, morphology, and optical properties of the synthesized composites were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy. The photocatalytic activity was assessed by degrading methylene blue under UV light irradiation. The results indicate that the incorporation of graphene oxide significantly improves the charge separation efficiency and extends the light absorption range of TiO2. The TiO2-graphene oxide nanocomposite demonstrated an enhanced photocatalytic degradation rate of methylene blue compared to pure TiO2. This study concludes that TiO2-graphene oxide composites are a promising material for environmental remediation applications, offering a sustainable approach to pollutant degradation.
