摘要

电氧化生物质衍生的5-羟甲基糠醛（HMF）是一种绿色且经济可行的生产有价值的化学品2,5-呋喃二羧酸（FDCA）的方法。鉴于这一转变的重要性，迫切需要高效的电催化剂来加速HMF的电氧化。本文全面综述了将HMF转化为FDCA的催化剂的电氧化机理、结构-性能相关性和优化策略。首先，讨论了反应途径的选择性、电氧化机制、控制HMF氧化的热力学和动力学原理，以及阻碍竞争性析氧反应的策略。随后，详细介绍了贵金属和过渡金属电催化剂的结构-性能相关性，强调了各种金属元素对HMF氧化过程的促进作用。此外，还深入分析了电催化剂的性能优化策略，包括定制表面吸附、调节脱氢、加速质子转移、整合催化位点和再生活性物质。此外，我们批判性地评估了目前在开发高效HMF电氧化催化剂方面面临的挑战，并提出了克服这些障碍的未来方向。本文旨在为开发高效电催化剂加快生物质转化应用提供有益的启示。

Refining Electrocatalyst Design for 5-Hydroxymethylfurfural Oxidation: Insights into Electrooxidation Mechanisms, Structure–Property Correlations, and Optimization Strategies

Electrooxidation of biomass-derived 5-hydroxymethylfurfural (HMF) is a green and economically viable approach to produce the valuable chemical 2,5-furandicarboxylic acid (FDCA). Given the significance of this transformation, there is a pressing demand for efficient electrocatalysts to expedite the HMF electrooxidation. This article provides a comprehensive overview of the electrooxidation mechanisms, structure–property correlations, and optimization strategies for catalysts involved in converting HMF into FDCA. Initially, the selectivity of reaction pathways, electrooxidation mechanisms, and thermodynamic and kinetic principles governing HMF oxidation are discussed, along with strategies to hinder the competitive oxygen evolution reaction. Subsequently, the structure–property correlations of electrocatalysts based on precious metals and transition metals are introduced in detail, emphasizing the promotion effects of various metal elements on the HMF oxidation process. Furthermore, an in-depth analysis of performance optimization strategies for electrocatalysts is also conducted, including tailoring surface adsorption, regulating dehydrogenation, accelerating proton transfer, integrating catalytic sites, and regenerating active species. Additionally, we critically assess the current challenges faced in developing highly effective HMF electrooxidation catalysts and propose future directions for overcoming these obstacles. This review article aims to provide insightful inspiration for developing high-efficiency electrocatalysts to expedite biomass conversion applications.
