“…These results probably resulted from the fact that the heteroatom-doping in the carbon matrix could promote the dispersion of metal nanoparticles and reduce the particle size of the metal nanoparticles, leading to higher surface energy and maximum utilization of the noble metal atoms, thus improving their catalytic activity. Meanwhile, Li et al 41 discovered that the aerobic oxidation of HMF to FDCA could be achieved under mild conditions over Pd/VC with a high NaOH content. They also found that the oxidation of HMF was greatly affected by the oxygen content.…”

“…[17] While Pd loaded on carbon in aqueous NaOH results in 99 % 5-HMF conversion and 92.4 % FDCA yield at only 30 °C in 3 h under flowing O 2 . [18] In comparison, 100 % 5-HMF conversion was achieved with approximately 90 % FDCA yield in 4 h over Au/C catalyst in aqueous NaOH solution at 70 °C and 10 bar O 2 pressure. [19] The deployment of bimetallic catalysts for 5-HMF selective oxidation has also shown to be beneficial, especially bimetallic catalysts based on Au, with enhancements including increased activity, selectivity, and catalyst stability.…”

Synthesis of 2,5‐furandicarboxylic acid (FDCA) can be achieved via catalytic oxidation of 5‐hydroxymethylfurfural (5‐HMF), in which both base and catalyst play important roles. This work presents the development of a simple synthesis method (based on a commercial parent 10 wt.% Pd/C catalyst) to prepare the bimetallic AuPd alloy catalysts (i. e., AuPd/C) for selective 5‐HMF oxidation to FDCA. When using the strong base of NaOH, Pd and Au cooperate to promote FDCA formation when deployed either separately (as a physical mixture of the monometallic Au/C and Pd/C catalysts) or ideally alloyed (AuPd/C), with complete 5‐HMF conversion and FDCA yields of 66 % vs 77 %, respectively. However, NaOH also promoted the formation of undesired by‐products, leading to poor mass balances (<81 %). Comparatively, under weak base conditions (using NaHCO3), an increase in Au loading in the AuPd/C catalysts enhances 5‐HMF conversion and FDCA productivity (due to the enhanced carbonyl oxidation capacity) which coincides with a superior mass balances of >97 %. Yet, the excessive Pd content in the AuPd/C catalysts was not beneficial in promoting FDCA formation.

Biomass assumes an increasingly vital role in the realm of renewable energy and sustainable development due to its abundant availability, renewability, and minimal environmental impact. Within this context, 5‐hydroxymethylfurfural (HMF), derived from sugar dehydration, stands out as a critical bio‐derived product. It serves as a pivotal multifunctional platform compound, integral in synthesizing various vital chemicals, including furan‐based polymers, fine chemicals, and biofuels. The high reactivity of HMF, attributed to its highly active aldehyde, hydroxyl, and furan ring, underscores the challenge of selectively regulating its conversion to obtain the desired products. This review highlights the research progress on efficient catalytic systems for HMF synthesis, oxidation, reduction, and etherification. Additionally, it outlines the techno‐economic analysis (TEA) and prospective research directions for the production of furan‐based chemicals. Despite significant progress in catalysis research, and certain process routes demonstrating substantial economics, with key indicators surpassing petroleum‐based products, a gap persists between fundamental research and large‐scale industrialization. This is due to the lack of comprehensive engineering research on bio‐based chemicals, making the commercialization process a distant goal. These findings provide valuable insights for further development of this field.This article is protected by copyright. All rights reserved
