Abstract ：The intermediate phase of hydrothermal synthesis of the Na0.44 MnO2 (NMO) nanowires is systematically investigated by means of transmission electron microscopy (TEM). The coexistence of Na-birnessite and NMO is commonly observed in the nanosheets. The NMO nanobelts in general have the width of ～ 15 nm embedded in the (001) oriented Na-birnessite nanosheet. It is also found that the nanosheets of this intermediate phase often split along the NMO and Na-birnessite interface. Our structural study also shows that the NMO nanobelts prefer to grow along the [001] direction and gives rise to the [001] elongated NMO nanowires. Based on our TEM observations, the visible lattice mismatch and the resultant strain at the NMO/Na-birnessite interface play a critical role for formation of notable splitting structures in this kind of nanomaterial. The mechanism for the formation of the [001] NMO nanobelt is briefly discussed.
