(a) Truncated octahedral bipyramidal anatase TiO2 single crystals with exposed {001} and {101} facets. (b) Polyhedral anatase TiO2 single crystals exposed with {001}, {101} and {112} facets. (c) Polyhedral anatase TiO2 single crystals enclosed with {001}, {101} and quasi continuous microfacets. (d) Round anatase TiO2 single crystals exposed with {001} and quasi continuous microfacets. (e) Round anatase TiO2 single crystals only exposed with quasi continuous microfacets. Scale bars are 1 μm. All crystals were synthesized in 5.33 mM TiF4 aqueous solution with 0 g (a), 0.8 g (b), 1.5 g (c), 3 g (d) and 6 g (e) of CA at 180 °C for 20 h. Panels f–j are corresponding geometric models shown in a–e.
