Abstract:
Graphite oxide, as a promoter in TiO2- P25 (GOTiO2) and Ag- doped TiO2 (GOAgTiO2) photocatalysts, was synthesized via modified Hummers method and was characterized by XRD, Raman spectrometry and TEM. Ag nanoparticle, in AgTiO2 and GOAgTiO2, was prepared using a photoreduction/ ultrasonication technique, and was confirmed by XRD, SEM and TEM. AgTiO2, GOTiO2 and GOAgTiO2 with 2, 5, 10% Ag and 0.5, 15% GO in TiO2 were used as photocatalysts for Rhodamine B (RhB) destruction for 2 h reaction time. The catalyst; 0.5GO5AgTiO2 performed the best synergetic result of 79% RhB destruction. Cyclic voltammetric (CV) measurement of the prepared photocatalyst electrodes confirmed that the small amount of Ag (5%) and GO (0.5%) promoted the photo- excited electron transportation in 0.5GO5AgTiO2. Electrochemical impedance spectroscopy (EIS) of RhB destruction on the best two photocatalyst electrodes (15GOTiO2 and 0.5GO5AgTiO2) compared with TiO2 under irradiation, the results showed that charge transfer resistance (Rct) of 0.5GO5AgTiO2 changed much from that in the dark, indicating the oxidation destruction of RhB. The suitable electrode material, used for developing TiO2 to be a smart catalyst for detection of RhB destruction and sensing, should be 0.5GO5AgTiO2
