N2 - A simple hydrothermal technique was used to incorporate nanographene platelets (NGP) with CeO2/TiO2 composites with different NGP contents. The prepared samples were then evaluated as a heterogeneous catalyst to degrade methylene blue (MB) under visible light irradiation, ultrasonic irradiation, and a combination of the two. The structural and morphological properties of CeO2/TiO2/NGP composites were investigated by X-ray diffraction (XRD). The XRD spectra of CeO2/TiO2/NGP revealed the spectra of NGP, CeO2, and TiO2 nanoparticles indicating the desired combination. Further investigation using TGA measurements show that weight was lost at around 600 °C due to the combustion of carbon. The surface area of the composites was further increased. The prepared CeO2/TiO2-10 wt.% NGP composites were able to degrade MB four times higher than pristine CeO2/TiO2 composites, which may be due to a lower recombination rate; however, further increments of NGP decreased the degradation efficiency.
