Figure 1. (A) Schematic of the synthetic procedure for the synthesis of GTx HPJs from intermediates Gx (x is the molar ratio of glucose to TBOT, x = 0, 5, 15, 20, 30, 35); (B) XRD patterns of GTx HPJs; (C) The linear relationship between the mass fraction of rutile phase and G/Ti in GTx HPJ with glucose microcrystal as raw material; (D) Raman spectra with excitation line at 514 nm for GTx HPJs; (E) HRTEM images of GT0, (F) GT15 and (G) GT35; (H-S) show the close observations to the areas highlighted by yellow and cyan boxes in Figure 1E-G. TBOT: Titanium butoxide; XRD: X-ray diffraction; HRTEM: high-resolution transmission electron microscopy; GTx HPJs: anatase/rutile TiO₂ hetero-phase junctions.
