为了制备高产率的2，5-呋喃二甲酸（FDCA），以纳米金属氧化物CuO和Co₃O₄为催化剂，次氯酸钠为氧化剂，在常温常压条件下催化氧化生物质基化合物5-羟甲基糠醛（5-HMF）合成2，5-呋喃二甲酸，并探讨得到了最佳反应条件。在最佳反应条件下制得目标产物2，5-呋喃二甲酸的总收率为98%。催化剂CuO和Co₃O₄表现出优异的催化性能，同时CuO的循环稳定性良好，循环5次后仍能保持较高的活性，表明CuO作为催化剂在该体系中具有广阔的前景。

In order to prepare 2,5-furandicarboxylic acid in high yield,nano metal oxides CuO and Co₃O₄ are used as catalysts,and sodium hypochlorite is used as an oxidant to catalyze the oxidation of the biomass-based compound 5-hydroxymethylfurfural under atmospheric pressure and room temperature conditions.The optimal reaction conditions are also explored and gained.The total yield of 2,5-furandicarboxylic acid reaches 98% under the optimum reaction conditions.Both CuO and Co₃O₄ show excellent catalytic performance.The circulation stability of CuO is good and its activity remains relatively high after 5 cycles,indicating that CuO as a catalyst has a broad prospect in the system.
