摘要

生物质废弃物的升级利用一直是环境保护的永恒话题。从废弃作物中提取的5-羟甲基糠醛（HMF）可氧化为2,5 -呋喃二羧酸（FDCA），是一种高附加值的化学物质，但电催化剂尚未得到解决。本文合成了一种无金属电催化剂C42H26N12 NAR，并通过电催化HMF氧化反应（e-HMFOR）成功地将HMF转化为FDCA，同时在10 mA cm−2下将总水分解电压降低至1.24 V。此外，C42H26N12 NAR在1 M KOH + 0.1 M HMF中表现出良好的稳定性。本研究为设计e-HMFOR生成FDCA的碳基电催化剂提供了一种简便的策略。

Nitrogen-containing aromatic ring organic materials for electrocatalytic 5-hydroxymethylfurfural oxidation

Biomass waste upcycling has been always an eternal topic for environmental protection. 5-hydroxymethylfurfural (HMF) derived from wasted crops can be oxidized as 2, 5-furandicarboxylic acid (FDCA) that is a high-value-added chemical, but the electrocatalyst still remains unsolved. Herein, a metal-free electrocatalyst C₄₂H₂₆N₁₂ NAR was synthesized and successfully converted HMF to FDCA through electrocatalytic HMF oxidative reaction (e-HMFOR), meanwhile reducing the overall water splitting voltage as only 1.24 V at 10 mA cm⁻². Besides, the C₄₂H₂₆N₁₂ NAR exhibits good stability in 1 M KOH + 0.1 M HMF. This study provides a facile strategy to design carbon-based electrocatalyst for e-HMFOR to generate FDCA.
