Fig. 4 Morphology and atomic structure of anatase TiO 2 crystals [ 32 ] a Schematic of anatase TiO 2 with different percentages of #cod#x0007b;101#cod#x0007d;, #cod#x0007b;001#cod#x0007d;, and #cod#x0007b;010#cod#x0007d; facets. b-d SEM images of anatase crystals synthesized with different aqueous solutions of HF 120, 80, and 40 mm containing different amounts of TiOSO 4 precursor 64, 32, and 32 mg at 180℃ for different times 12, 12, and 2 h. The samples shown in b-d are denoted T001-F, T101-F, and T010-F, where T indicates TiO 2 , 001101010 the dominant facet, and F surface-terminating fluorine. e, f, h TEM images of representative particles of T001-F, T101-F, and T010-F. g HRTEM image recorded from typical T001-F particle with [001] orientation. i, k HRTEM images recorded from another T010-Fparticle along the [110] and [010] zone axis. j, l Projected atomic models along [110] and [010] directions; white Ti 4+ , black O 2-
