Photocatalytic removal of phenol over titanium dioxide- reduced graphene oxide photocatalyst
Titanium dioxide (TiO2) has been one of the most investigated semiconductors due to its high activity for the removal of organic pollutants. In order to improve the efficiency of the TiO2, series of TiO2-reduced graphene oxide (rGO) composites with various loading amounts of graphene oxide (GO), whi...

Titanium dioxide (TiO2) has been one of the most investigated semiconductors due to its high activity for the removal of organic pollutants. In order to improve the efficiency of the TiO2, series of TiO2-reduced graphene oxide (rGO) composites with various loading amounts of graphene oxide (GO), which were 0.5, 1, 3 and 5 wt% were prepared by UV- assisted photocatalytic reduction method. The X-ray diffraction (XRD) patterns and Fourier transform infrared spectroscopy (FTIR) spectra confirmed that all the TiO2-rGO composites samples were successfully synthesized without disrupting the structure of the TiO2. Fluorescence spectroscopy revealed the role of the rGO to reduce the electron-hole recombination on the TiO2, while the transmission electron microscopy-energy dispersive X- ray spectroscopy (TEM-EDS) confirmed the morphology and the presence of both TiO2 and rGO. In the photocatalytic removal of phenol, all the TiO2-rGO composites showed better photocatalytic activities than the TiO2 under UV light irradiation. The activity of the TiO2 was enhanced by more than two times with the addition of the GO with the optimum amount (3 wt%). It was proposed that the good photocatalytic performance obtained on the composites were caused by the successful suppression of electron-hole recombination by the rGO on the TiO2. |
