Abstract

The aerobic oxidation of 5-hydroxymethylfurfural (HMF) into 2,5-furandicarboxylic acid (FDCA), a bio-based plastic monomer, is an important process for the valorization of biomass. Here, manganese oxides of various oxidation states with identical morphologies and similar surface areas were synthesized by introducing oxygen vacancy sites, and they were investigated as heterogeneous catalysts for HMF oxidation. Mn₂O₃ exhibited a remarkable catalytic efficiency due to synergistic effect of the oxidation state of metal moieties, the basicity of the catalyst, and oxygen mobility of the oxide materials under basic condition.

提高锰催化5-羟甲基糠醛有氧氧化效率的策略

5-羟甲基糠醛（HMF）的好氧氧化生成2,5-呋喃二羧酸（FDCA）是生物基塑料单体，是生物质再生的重要过程。本文通过引入氧空位，合成了具有相同形貌和相似表面积的不同氧化态的锰氧化物，并对其作为HMF氧化的多相催化剂进行了研究。由于金属基团的氧化态、催化剂的碱度和氧化物材料的氧迁移率在碱性条件下的协同作用，Mn2O3表现出了显著的催化效率。
