FTIR analysis. FTIR spectroscopy was employed to identify different oxygen functionalities on graphene oxide and TiO 2 /GO composites. The FTIR spectra of graphene oxide and TiO 2 /GO nanocomposites is depicted in Fig. FTIR range of 300 to 4000 cm −1 was selected for the comparison. The most intense peak at about 3407 cm −1 is ascribed to the stretching vibrations of O H group ...
