Abstract The electrocatalytic upgrading of 5‐hydroxymethylfurfural (HMF, 5‐(Hydroxymethyl) furan‐2‐carbaldehyde) has emerged as a renewable and environmentally friendly means for the production high‐value chemicals, with oxidation product furan‐2,5‐dicarboxylic acid (FDCA, 2,5‐furandicarboxylic acid) possessing economic viability in substituting terephthalic polymer synthesis. This article reviews recent advancements selective HMF to FDCA, including reaction pathways, mechanisms, well activity descriptors (HMFOR), alongside advanced operando characterization techniques. Subsequently, representative HMFOR catalysts, encompassing noble metal, non‐noble transition metal‐based catalysts metal free‐based are presented. Then strategies regulating longevity were introduced, followed by an exploration future prospects development catalysts.

As a type of sustainable and renewable natural source, biomass-derived 5-hydroxymethyl furfural (HMF) can be converted into high-value chemicals. This study investigated the interactions between silver (Ag) oxide supports with varied reducibility their contributions to tuning catalytic performance in selective oxidation HMF. Three representatives manganese dioxide (MnO2), zirconium (ZrO2), silicon (SiO2) were selected support Ag active sites. The catalysts characterized by techniques such as STEM (TEM), Raman, XPS, H2-TPR, FT-IR spectroscopy explore morphology, dispersion, surface properties, electronic states. results demonstrated that MnO2 highest exhibited superior performance, achieving 75.4% HMF conversion 41.6% selectivity for 2,5-furandicarboxylic acid (FDCA) at 120 °C. In contrast, ZrO2 SiO2 limited capabilities, mainly producing intermediate products like FFCA and/or HMFCA. ability these was governed reducibility, because it determined density oxygen vacancies (Ov) hydroxyl groups (OOH), eventually influenced activity, reaction rate: Ag/MnO2 (3214.5 molHMF·gAg−1·h−1), Ag/ZrO2 (2062.3 Ag/SiO2 (1394.4 molHMF·gAg−1·h−1). These findings provide valuable insights rational design high-performance chemical conversion.
