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…
