本发明属功能材料制备技术领域，涉及种三氧化二锰/二氧化锡复合纳米材料的制备方法，向草酸水溶液中滴加氯化锰与氯化亚锡混合物的甲醇溶液，在恒温并且搅拌的条件下反应直到前驱物沉淀生成，过滤、水洗、干燥，然后在马弗炉进行热处理即获得三氧化二锰/二氧化锡复合纳米材料。本发明工艺简便易行，纯度高，杂质含量低，产品制备成本低，性能优异，可以工业化批量生产。本发明所制备的三氧化二锰/二氧化锡复合纳米材料的导电性较好，作为电极材料使用具有较高的比电容，和良好循环性能。 The invention belongs to the technical field of preparation of functional materials, and relates to a preparation method of a manganese oxide/tin dioxide composite nanomaterial. The method comprises the steps of dropwise adding a methanol solution of a manganese chloride and stannous chloride mixture to an oxalic acid aqueous solution and carrying out reaction at a constant temperature under a stirring condition until a precursor sediment is generated; and carrying out filtering, washing and drying and then carrying out thermal treatment in a muffle furnace to obtain the manganese oxide/tin dioxide composite nanomaterial. The technology is simple, convenient and feasible, the purity is high, the impurity content is low, the preparation cost of a product is low, the performance is excel
