427MnO2nmTEMThe size of MnO2 nanosheets was found to be around 280 nm while the heights were about 5.6 nm
579MnO2μmTEM, SEMFigure 2 shows that all of the MnO2 samples were assembled to form the same morphology, nanorods. α-MnO2 nanorods were 15–95 nm in diameter and 0.27–1.3 μm in length. β-MnO2 nanorods were 40–130 nm in diameter and 0.64–2.78 μm in length. γ-MnO 2 nanorods were 18–105 nm in diameter and 0.2–0.7 μm in length.33.700000000000003
