Figure 2. Schematic representation of the polyol-solid surface/interface transesterification strategy used to construct intermediate Gx in different states to regulate the phase composition. Synthesis methods: (A1) uncomplexed TBOT, (B1-D1) the transesterification reaction between TBOT and glucose surface/interface resulted in the formation of GTC with different amounts of TBOT adsorbed on the surface; (E1) Intermediate pure GTC of GT35, which is completely transesterification reactive on the glucose surface/interface and contains no TBOT; (A2) Amorphous TiO₂ G0 formed after hydrolysis of TBOT in air; (B2-E2) Intermediates G5, G15, G30, and G35; (A3) Anatase TiO₂ formed from amorphous TiO₂ by annealing in air; (B3-D3) A/R TiO₂ HPJs with different phase mass ratios formed by annealing in air to remove glucose. (E3) Rutile TiO₂ formed by annealing in air. TBOT: Titanium butoxide; GTC: glucose-Ti complexes.
