The alpha-MnO2 nanocrystal nanowires, nanoplates, and nanoflowers have been successfully synthesized by a common hydrothermal treatment of different solutions containing KMnO4 and NH4X (X = Cl-, Ac-, NO3-, SO4(2-), and PO4(3-)) at 140 degrees C for 24 h. The influence of anions on the morphology of final product is discussed. According to our experimental results, we proposed a possible mechanism of the formation of different morphologies of nano-phase alpha-MnO2 and considered that the growing process was due to the initial plate-like MO(x) absorbing different anions and cooperation with them, which contributes to the final morphology of the product.
通过在140℃下对含有KMnO₄和NH₄X（X = Cl⁻、Ac⁻、NO₃⁻、SO₄²⁻和PO₄³⁻）的不同溶液进行24小时的常规水热处理，已成功合成了α-MnO₂纳米晶体纳米线、纳米片和纳米花。讨论了阴离子对最终产物形态的影响。根据我们的实验结果，我们提出了纳米相α-MnO₂不同形态形成的可能机制，并认为生长过程是由于初始的板状MO(x)吸收不同的阴离子并与它们协同作用，这有助于产物的最终形态。
