The aerobic oxidation and oxidative esterification of 5‐hydroxymethylfurfural (HMF) catalyzed by gold nanoparticles (AuNPs) supported on a semicrystalline nanoporous multiblock copolymer matrix consisting of syndiotactic poly(styrene)‐cis‐1,4‐poly(butadiene) (sPSB) have been investigated. Depending on the reaction parameters (support nanoporosity, presence of water, solvent, temperature, cocatalyst, oxygen pressure), the conversion of HMF can be finely addressed to the formation of the desired oxidation product, such as 2,5‐diformylfuran (DFF), 5‐formylfuran‐2‐carboxylic acid (FFCA), methyl 5‐(hydroxymethyl)furan‐2‐carboxylate (MHMFC), dimethyl furan‐2,5‐dicarboxylate (DMFC), and furan‐2,5‐dicarboxylic acid (FDCA), under optimized reaction conditions. The AuNP–sPSB catalyst is highly effective and selective because the polymer support acts as a conveyor and concentrator of the reactants toward the catalytic sites.

纳米多孔聚合物基质上负载的金纳米颗粒对5-羟甲基糠醛的好氧氧化和氧化酯化

金纳米颗粒（AuNP）催化由间同立构聚（苯乙烯）顺式组成的半结晶纳米多孔多嵌段共聚物基质上催化的5-羟甲基糠醛（HMF）的需氧氧化和氧化酯化-1,4-聚丁二烯（sPSB）已进行了研究。根据反应参数（支持纳米多孔性，水，溶剂，温度，助催化剂，氧气压力）的不同，HMF的转化可以精细地处理以形成所需的氧化产物，例如2,5-二甲酰呋喃（DFF），5-甲酰基呋喃-2-羧酸（FFCA），5-（羟甲基）呋喃-2-羧酸甲酯（MHMFC），呋喃-2-5,2-二羧酸二甲酯（DMFC）和呋喃-2,5-二羧酸（ FDCA），在优化的反应条件下。AuNP–sPSB催化剂非常高效且具有选择性，因为聚合物载体充当了反应物向催化部位的输送带和浓缩器。
