▎ 摘  要

NOVELTY - Preparing manganese oxide-carbon composite material with branched structure, comprises dissolving slightly excess potassium permanganate in water, adding manganese sulfate and uniformly mixing, continue to reacting under stirring to form manganese oxide colloid that absorbs excessive high-valent manganate ions, adding carbon-based materials and uniformly mixing with the colloid, placing into a closed reaction kettle and heating for reaction, and the molar ratio of the potassium permanganate to manganese sulfate is 0.67-0.76. USE - The method is useful for preparing manganese oxide-carbon composite material with branched structure. ADVANTAGE - The method reduces the oxidation activity of the oxidant, and improves the selectivity of in-situ graft. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manganese oxide-carbon composite material with branched structure.
