Pd/CC catalyst was synthesized from readily available biomass-derived d-glucose. The catalyst was characterized using various techniques such as Fourier transform infrared spectroscopy, powder X-ray diffraction, energy dispersive X-ray analysis, scanning electron microscopy, ¹³C cross polarization NMR, transmission electron microscopy, X-ray photoelectron spectroscopy, and Brunauer–Emmett–Teller (BET) surface area analysis. This catalyst showed excellent catalytic activity toward the synthesis of industrially important 2,5-furandicarboxylic acid (FDCA) from 5-hydroxymethylfurfural (HMF) and fructose. The process is simple, efficient, green, and industrially feasible. Oxidation of HMF proceeded in 85% yield, and dehydration of fructose followed by oxidation gave 64% yield of FDCA with 100% purity using Pd/CC catalyst and molecular O₂ as an oxidizing agent under aqueous reaction conditions. The one pot two step procedure is highly efficient for synthesis of FDCA from fructose as it avoids isolation of HMF and requires a single catalyst for two different steps. FDCA finds utility in next-generation bioplastic poly(ethylene 2,5-furandicarboxylate) (PEF), which is a replacement for fossil-fuel-based poly(ethylene terephthalate) (PET).

Pd / CC催化剂在水性条件下由5-羟甲基糠醛和果糖合成2,5-呋喃二甲酸的有效方法

从容易获得的生物质衍生的d-葡萄糖合成Pd / CC催化剂。使用多种技术对催化剂进行了表征，例如傅立叶变换红外光谱，粉末X射线衍射，能量色散X射线分析，扫描电子显微镜，¹³C交叉极化NMR，透射电子显微镜，X射线光电子能谱和Brunauer-Emmett-Teller（BET）表面积分析。该催化剂对从5-羟甲基糠醛（HMF）和果糖合成工业上重要的2,5-呋喃二甲酸（FDCA）表现出优异的催化活性。该过程简单，高效，绿色且在工业上可行。HMF的氧化产率为85％，果糖脱水然后氧化，使用Pd / CC催化剂和分子O _2可以得到100％纯度的FDCA，产率为64％。在水性反应条件下作为氧化剂。一锅两步程序对于从果糖合成FDCA非常有效，因为它避免了HMF的分离，并且对于两个不同的步骤都需要使用一种催化剂。FDCA在下一代生物塑料聚（2,5-呋喃二甲酸乙二醇酯）（PEF）中得到了应用，该替代品替代了基于化石燃料的聚对苯二甲酸乙二醇酯（PET）。
