The beta-MnO2 three-dimensional (3D) nanostructures were synthesized in large area by a mineralizer-assisted hydrothermal route. KNO3 was introduced as inorganic mineralizer to direct the growth of beta-MnO2 3D nanostructures from Mn(NO3)2 solutions. The samples were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM). Possible growth mechanism of beta-MnO2 3D nanostructures was proposed based on comparative experiments, indicating that KNO3 mineralizer and the concentration of Mn(NO3)2 solution were the two decisive factors in the fabrication of beta-MnO2 3D nanostructures.
通过矿化剂辅助水热法大面积合成了β-MnO₂三维（3D）纳米结构。引入KNO₃作为无机矿化剂，以引导β-MnO₂ 3D纳米结构从Mn(NO₃)₂溶液中生长。通过X射线衍射（XRD）、场发射扫描电子显微镜（FESEM）和透射电子显微镜（TEM）对样品进行了表征。基于对比实验提出了β-MnO₂ 3D纳米结构可能的生长机制，表明KNO₃矿化剂和Mn(NO₃)₂溶液的浓度是制备β-MnO₂ 3D纳米结构的两个决定性因素。
