Figure 2. Charge difference distribution between different BiOBr crystal facets [(A) 110 facets and (B) 001 facets] and toluene (insets are the side views and 2D displays), with charge accumulation in cerulean blue (Prussian blue in 2D displays) and depletion in yellow (red in 2D displays). HRTEM images of BiOBr crystals with (001) planes (C,E), and a mixture of (001) and (110) planes (D,F).
