The invention relates to a method for preparing a carbon-containing bimetallic oxide. The method for preparing a carbon-containing bimetallic oxide comprises the steps of: reacting potassium permanganate with iron, cobalt or nickel transition metal oxide precursor and unsaturated long-chain fatty acid to directly synthesize a nano-scale bimetallic oxide material inlaid in a carbon matrix. Throughthe combination of a micro-emulsification technology and a Baeyer reagent reaction route, the type and the proportion of metal salt, the type and the proportion of unsaturated long-chain fatty acid, aheating method, a roasting atmosphere and a roasting temperature are precisely adjusted, and the bimetallic oxide is directly inlaid into the carbon matrix to obtain the carbon-containing nano-scalebimetallic composite oxide with the controllable structure, the component content and the component type. 本发明涉及一种含碳双金属氧化物的制备方法，用高锰酸钾与铁、钴或镍过渡金属氧化物前驱体及不饱和长链脂肪酸反应，直接合成嵌入在碳基质中的纳米级双金属氧化物材料。通过微乳化技术结合Baeyer试剂反应路线，精确调变金属盐种类及其比例、长链不饱和脂肪
