图5 纳米多孔Au-Pt表面偏聚的3D分析

Fig.5 3D analyses of surface segregation in nanoporrous Au-Pt (The thickness of the slices is 1 nm) (a) 3D reconstruction of the void in the surface (b) 3D reconstruction of Pt distribution around the void in Fig.5a (The color represents the intensity of the EDS signal of the Pt element, which gradually becomes more intense from blue to green) (c-f) multiple slices of 3D reconstructed chemical composition distribution on the surface of the void in Fig.5a (Crystallog-raphic planes with different indexes are determined and indicated)
