Research progress of chemical manganese dioxide

综述了化学二氧化锰的制备、应用等方面的研究进展和现状。介绍了几种常用的制备方法,包括:碳酸锰热分解法、硝酸锰热分解法、溶液氧化还原法,以及纳米二氧化锰的制备方法,并分析了这些制备方法的特点。目前化学二氧化锰的主要工业生产方法是碳酸锰热分解法、硝酸锰热分解法和硫酸锰-高锰酸钾氧化还原法。纳米二氧化锰的制备及其应用是未来化学二氧化锰研究的重要发展方向。

Research progress and present status of preparation and application of chemical manganese dioxide { CMD } were reviewed. Several common preparation methods , such as manganese carbonate thermal decomposition method , manganese nitrate thermal decomposition method, solution oxidation - reduction method, and nano - MnO2 preparing method w were introduced,and advantages and disadvantages of these methods were analyzed. At present, the main industrial production methods of CMD are manganese carbonate thermal decomposition method, manganese nitrate thermal decomposition method, and manganese sulfate-potassium permanganate oxidation-reduction method. Preparation and application of nano - MnO2 are important developing directions of CMD.
