Facile Synthesis of Nanostructured Anatase Titania with Controllable Morphology via Oxidation of TiC with Hydrogen Peroxide

Figure 2

(a) TEM image for the acidic powder obtained after the oxidation of TiC with H₂O₂ for 10 hours, displaying the meshed network of entwining 2D nanosheets. (b) HRTEM image of a 2D nanosheet, demonstrating the observable atomic fringes. Inset on the left lower corner is the SAED, showing the diffraction rings. Inset on the right top corner is the RT XRD of acidic powder in (a), demonstrating the amorphous state. (c) SEM image for the nanostructured anatase TiO₂ obtained by annealing the amorphous acidic powder in (b) at 350°C for 2 hours. (d) RT Raman (top) and XRD pattern (bottom) for the annealing-produced anatase TiO₂ in (d).
