Electrochemical oxidation of biomass-derived 5-hydroxymethylfurfural (HMF) is a promising way to produce 2,5-furandicarboxylic acid (FDCA). Here, a flowerlike hybrid composed of sulfur-modulated metallic nickel nanoparticles coupled with carbon frameworks (S–Ni@C) is synthesized via two steps, achieving high selectivity and efficiency for HMF oxidation. Lignosulfonate, which is pulp waste, is used as a carbon and sulfur precursor. The optimized S–Ni@C electrode exhibits a nearly 100% conversion of HMF, 96% yield of FDCA, and 96% high faradaic efficiency. This work provides insights into the design and synthesis of electrocatalysts for biomass upgrading.

由木质素磺酸盐制备硫调节的镍/碳复合材料，用于5-羟基甲基糠醛电催化氧化为2,5-呋喃二甲酸

生物质衍生的5-羟甲基糠醛（HMF）的电化学氧化是生产2,5-呋喃二甲酸（FDCA）的一种有前途的方法。在这里，通过两个步骤合成了由硫调节的金属镍纳米粒子与碳骨架（S–Ni @ C）组成的花状杂化体，实现了HMF氧化的高选择性和高效率。木浆废料木质素磺酸盐被用作碳和硫的前体。经过优化的S-Ni @ C电极具有近100％的HMF转化率，96％的FDCA产率和96％的高法拉第效率。这项工作提供了用于生物质升级的电催化剂设计和合成的见解。
