在可持续发展导向下,替代能源需求不断增加,生物质资源的有效利用成为研究焦点。5-羟甲基糠醛(HMF)作为一种生物质基平台化合物,具有广阔的应用前景。通过选择性氧化反应,HMF可以转化为高附加值化合物,如2,5-呋喃二甲酸(FDCA)。近年来,电催化氧化作为一种绿色环保的新型手段,在HMF转化为FDCA的研究中取得了显著进展。然而,这一过程涉及竞争反应,如水氧化,对FDCA的产率和法拉第效率产生影响。催化剂对降低反应能垒、提高产物选择性至关重要,但面临稳定性不足、过电位偏高和酸性环境下活性不足等挑战。聚焦于高效催化剂的研究进展,从贵金属催化剂到非贵金属催化剂和非金属催化剂进行深入探讨,旨在为生物质的高效转化提供有益参考。

With the increasing demand of alternative energy for achieving sustainable development, the effective utilization of biomass resources has become a research focus. 5 - Hydroxymethylfurfural (HMF), as a biomass-based platform compound, has broad application prospects. It can be converted into high value-added compounds such as 2,5-furandicarboxylic acid (FDCA) through selective oxi dation. Electrooxidation, as a new green and environmentally friendly method, has made significant progress in the research of converting HMF to FDCA in recent years. However, this process involves competitive reactions, such as water oxidation, which affects the yield and Faradaic efficiency of FDCA. The catalyst is crucial for reducing reaction energy barriers and improving product selectivity, but it faces challenges such as insufficient stability, high overpotential, and insufficient activity in acid ic environments. This review focuses on the research progress of high-performance catalysts, exploring in depth from noble metal catalysts to non-noble metal catalysts and non-metal catalysts, aiming to provide useful references for the efficient conversion of biomass.
