titleOfInvention | Manganese dioxide, preparation method and application thereof |
abstract | The invention relates to manganese dioxide, a preparation method and application thereof. The preparation method comprises the following steps: (1) roasting the mixed material containing pyrolusite and acid to obtain roasted clinker; (2) carrying out a dissolution process on the roasted clinker to obtain a dissolved material; (3) mixing with an oxidant to obtain a mixed solution, and carrying out hydrothermal reaction on the mixed solution to obtain manganese dioxide. The method takes pyrolusite as a raw material, and controls the concentration of iron ions in a manganese sulfate solution by regulating and controlling the roasting temperature, so as to prepare nano manganese dioxide with different shapes; according to the invention, a reducing agent, a surfactant, a template and an iron-containing chemical reagent are not used in the process of preparing manganese dioxide, the preparation process is simple, easy to operate, economical and reasonable, the high value-added utilization of manganese ore resources is realized, the emission of wastes is reduced, and a new technology and theoretical support are provided for the efficient comprehensive utilization of low-grade pyrolusite. |
