摘要
5-羟甲基糠醛是一种重要的化学平台分子,是C6单糖的脱水产物,通过进一步转化可衍生出多种有用的化学产品和生物燃料。5-羟甲基糠醛的转化大多数是基于高温、高压、强碱的非均相催化。近年来发展的电化学催化,也主要集中于Au、Pd、Pt等贵金属催化剂的研究。我们通过水热法合成了高密集的非贵金属NiCo_2O_4纳米线,在600m V(vs SCE)恒电位下可实现HMF近100%的转化,并对DFF有较高的选择性。
5-hydroxymethylfurfural(HMF) is a key platform molecule that can generate valuable chemicals and biomass fuel. Previous works mainly focus on heterogeneous catalysis(high temperature or pressure), or on noble metal electrocatalytic oxidation. Here we prepare a NiC o2O4 nanowires catalyst, which has a nearly 100% HMF conversion and high DFF selectivity. This study propose a new method to make HMF oxidation become more efficient and economical.
