SEM and TEM images. (a) Low-magnification SEM image of Na_2-xMn₈O₁₆ nanorods; (b) high-magnification SEM image of Na_2-xMn₈O₁₆ nanorods; (c) TEM image of Na_2-xMn₈O₁₆ nanorods; (d) TEM image of a single Na_2-xMn₈O₁₆ nanorod; (e) HRTEM image of the Na_2-xMn₈O₁₆ nanorod, the inset of (e) is the corresponding SAED pattern of the nanorod. (f) EDS spectrum of the Na_2-xMn₈O₁₆ nanorods. C peak originates from conductive adhesive, Cu peak originates from Cu sheet, and Pt peaks originate from sputtered Pt layer. (a) scale bar 10 μm, (b) scale bar 5 μm, (c) (d) scale bar 500 nm, (e) 5 nm
