Highly photodegradation of organic dye pollutant RhB using TiO2-modified reduced graphene oxide

Abstract TiO2-modified reduced graphene oxide (TiO2-rGO) has been studied in one-process step synthesis via the hydrothermal method. In this study, the various concentrations of rGO were investigated and characterized by fourier transform infrared (FTIR), x-ray diffraction (XRD), scanning electron microscope (SEM), surface area analyzer (SAA), thermogravimetric analysis/differential thermal analysis (TGA/DTA), and spectroscopy UV-Vis. In addition, the photodegradation of rhodamine-B was studied by a batch system under visible light irradiation at wavelength 554 nm. The optimum experimental results showed that the presence of rGO in TiO2 nanostructures could improve the specific surface area until 248.58 m2 g− 1 and enhanced the photodegradation efficiency until 70.66% under visible light irradiation. The photocatalyst stability was evaluated for five cycles experiment and the performance have reduced 6.58% efficiency.
