(a) XRD spectra of B-TiO2−x samples with different B doping. (b) HRTEM image of 10% B-TiO2−x. In (b), a red dash line is drawn to outline the interface between the crystalline core and the disordered outer layer. (c) Raman spectra of pure TiO2 and B-TiO2−x samples with different B doping content. Inset: the most intense Eg peak at 142.5 cm−1, along with its center position and line width (Full Width at Half Maximum, FWHM).
