摘要: MnO2 hierarchical microsphere has been synthesized by a facile and direct hydrothermal reaction between KMnO4 HCl without the aids of catalysts, surfactants or templates. The as-prepared microsphere, as characterized x-ray diffraction (XRD), scanning electron microscopy (SEM), transmission (TEM) analysis nitrogen adsorption desorption, is in form K0.27MnO2 (H2O)(0.54), with flower-like structure BET surface area value 52 m(2)/g. morphology product can be simply tailed controlled temperature period crystallinity modified changing concentrate KMnO4. In general, excessive low are favor to forming structure. Besides, formation mechanisms schemes proposed.
