7658 427 MnO2 nm TEM The size of MnO2 nanosheets was found to be around 280 nm while the heights were about 5.6 nm
7807 579 MnO2 μm TEM, SEM Figure 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
