A facile hydrothermal method for the controllable synthesis of TiO₂ nanocrystals with tunable shapes

Abstract

Using OA and OM as the capping surfactants, a facile and harmless hydrothermal method was invented to prepare anatase TiO2 nanocrystals with exposed {101} facets.

Effects of crystallinity, {001}/{101} ratio, and Au decoration on the photocatalytic activity of anatase TiO2 crystals

“…Because the presence of Fions favors the formation of (001) exposed facets, the ratios of {001} to {101} exposed facets were calculated and are shown in Table 1. In order to calculate the {001}/{101} ratio, a schematic diagram of the anatase TiO2 structure [46] is shown in Fig. 3f.…”
