Fossil fuel consumption has caused petroleum shortages and increased carbon emissions; thus, utilizing renewable resources in biorefineries for biomass-derived chemical synthesis is promising. Among them, 2,5-furandicarboxylic acid (FDCA) is a key alternative to terephthalic acid (PTA) for sustainable polyester production. In this work, we demonstrate an efficient approach for the simultaneous production of FDCA while utilizing carbon dioxide (CO₂) via an electrochemical approach. Complete electrooxidation of hydroxymethylfurfural (HMF) at the anode yields FDCA, while CO₂ reduction at the cathode produces valuable compounds such as carbon monoxide (CO). This concurrent HMF electrooxidation and CO₂ electroreduction strategy enables high-value chemical production at mild conditions. In addition, we developed efficient single catalysts, FeNi metals supported on CO₂-derived multi-walled carbon nanotubes deposited on nickel foam (FeNiCNTs/NF) as both the anode and the cathode for HMF oxidation and CO reduction, respectively. Remarkably, faradaic efficiencies reached 99.60% for FDCA (FE) at the anode and 96.25% for CO (FE) at the cathode. This study highlights the effective use of synthesized non-noble metals supported on CO₂-derived CNTs for integrated biorefinery and CO₂ utilization.
化石燃料的消耗导致了石油短缺并增加了碳排放；因此，在生物炼制中利用可再生资源进行生物质衍生的化学合成具有广阔前景。其中，2,5-呋喃二甲酸（FDCA）是对苯二甲酸（PTA）用于可持续聚酯生产的关键替代品。在这项工作中，我们展示了一种通过电化学方法在利用二氧化碳（CO₂）的同时同步生产FDCA的有效方法。阳极上羟甲基糠醛（HMF）的完全电氧化产生FDCA，而阴极上的CO₂还原产生有价值的化合物，如一氧化碳（CO）。这种同时进行的HMF电氧化和CO₂电还原策略能够在温和条件下生产高价值化学品。此外，我们开发了高效的单催化剂，即负载在沉积于泡沫镍上的CO₂衍生多壁碳纳米管上的FeNi金属（FeNiCNTs/NF），分别作为HMF氧化和CO还原反应的阳极和阴极催化剂。值得注意的是，阳极上FDCA的法拉第效率达到99.60%，阴极上CO的法拉第效率达到96.25%。这项研究突出了合成的负载在CO₂衍生的碳纳米管上的非贵金属在集成生物炼制和CO₂利用方面的有效应用。
