Fig. S1 View of the one-dimensional chain of titanium glycolate (TG, Ti(OCH2CH2O)2) along the c
axis.
Fig. S2 Raman spectrum of the TiO2 nanowires prepared by using TG as the precursor. Raman peaks
centered approximately at 121, 240, 248, 295 and 469 cm−1 are attributed to the typical features of
TiO2-B phase. The additional five vibration modes marked by blue arrows are attributed to the anatase
TiO2 phase.
Fig. S3 TEM image of the TiO2-B nanowires prepared by using P25 as the precursor. The diameter of
TiO2-B nanowires from P25 is larger than that of TiO2-B nanowire from TG.
Fig. S4 Nitrogen adsorption-desorption isotherm and the pore size distribution of TiO2-B nanowires
synthesized from P25. Inset shows the BJH pore distribution curve of the TiO2-B nanowires.
Fig. S5 The initial two discharge-charge curves of the TiO2-B nanowires synthesized from P25 at a
current density of 50 mA g−1.
