Simultaneous upgrading of biomass derivatives on highly efficient nonprecious metal-electrocatalysts is still an unprecedented challenge. We propose an electrocatalytic reductive amination and simultaneous oxidation (ERAO) route to convert biomass-derived 5-hydroxymethylfurfural (HMF) into valuable 2-hydroxymethyl-5-(ethanolamine methyl)furan (HEMF) at the cathode side and 2,5-furandicarboxylic acid (FDCA) at the anode. Accordingly, the cathode and anode electrode materials of the ERAO electrolyzer are titanium-based metal–organic framework (Ti-MOF) cubes and NiCoFe-LDHs nanosheets, respectively. The overall ERAO shows very good performance with ∼68% conversion of HMF after 6 h reaction, which is closely related to the exposed N–Ti–O active center from Ti-MOF and porous structure in providing extra access to the internal sites. The good stability of these catalysts after ERAO was further investigated. This work provides a sustainable route for biomass upgrading using the highly efficient nonprecious metal electrocatalysts.

生物质衍生5-羟甲基糠醛的电催化还原胺化和同时氧化

在高效的非贵金属电催化剂上同时升级生物质衍生物仍然是一个前所未有的挑战。我们提出了一种电催化还原胺化和同时氧化 (ERAO) 路线,将生物质衍生的 5-羟甲基糠醛 (HMF) 在阴极侧转化为有价值的 2-羟甲基-5-(乙醇胺甲基)呋喃 (HEMF) 和 2,5-呋喃二甲酸酸(FDCA)在阳极。因此,ERAO电解槽的阴极和阳极电极材料分别为钛基金属有机骨架(Ti-MOF)立方体和NiCoFe-LDHs纳米片。整体 ERAO 表现出非常好的性能,反应 6 小时后 HMF 的转化率约为 68%,这与 Ti-MOF 暴露的 N-Ti-O 活性中心和多孔结构密切相关,为内部位点提供了额外的通道。进一步研究了这些催化剂在 ERAO 后的良好稳定性。这项工作为使用高效的非贵金属电催化剂进行生物质升级提供了一条可持续的途径。
