Production of 2,5-furandicarboxylic acid (FDCA) via aerobic oxidation of 5-hydroxylmethylfurfural (HMF) is promising but still challenging due to the unsatisfied activity and stability of catalyst. Herein, we prepared a composite of CeO₂ coated carbon supporting Pt catalyst and use it in the oxidation of HMF with assistance of Na₂CO₃. A high FDCA yield of 99.0 % was achieved on 5 %Pt/CeO₂ @C catalyst under the optimized condition. To reveal the functions of the CeO₂ and carbon coating, control experiments, catalyst characterizations and HMF adsorption experiment were conducted. Combining these results, a possible mechanism is proposed. The synergism between CeO₂ and carbon is proposed and the role of CeO₂ and carbon coating is discussed. CeO₂ is in charge of storage/release electrons to activate oxygen due to its superior redox ability, while carbon coating is responsible for adsorbing HMF and conducting electrons between CeO₂ core and carbon surface. In addition, the stability was also evaluated and after 5 recycles, the yield of FDCA did not change obviously.

通过 5-羟甲基糠醛 (HMF) 的有氧氧化生产 2,5-呋喃二甲酸 (FDCA) 是有希望的，但由于催化剂的活性和稳定性不令人满意，仍然具有挑战性。在此，我们制备了CeO _{2包覆碳负载Pt催化剂的复合材料，并将其用于在Na 2} CO ₃的辅助下氧化HMF 。在优化条件下，5%Pt/CeO ₂ @C 催化剂的 FDCA 收率高达 99.0% 。为了揭示CeO ₂和碳涂层的功能，进行了对照实验、催化剂表征和HMF吸附实验。结合这些结果，提出了一种可能的机制。CeO _{2之间的协同作用}提出了碳，并讨论了CeO ₂和碳涂层的作用。CeO ₂由于其优越的氧化还原能力而负责储存/释放电子以活化氧，而碳涂层负责吸附HMF并在CeO ₂核心和碳表面之间传导电子。此外，还对稳定性进行了评价，5次循环后，FDCA的收率没有明显变化。
