Abstract：

Electrochemical　biomass　upgrading　is　a　promising　substitute　for　oxygen　evolution　reaction　(OER)　to　generate　valuable　chemicals　in　conjunction　with　hydrogen　generation.　Pursuing　highly　efficient　and　durable　electrocatalysts　for　significant　concentration　levels　(≥　50　mM)　of　biomass　electrooxidation　remains　an　enduring　challenge.　Herein,　we　introduce　a　robust　Cu-supported　CoFe　Prussian　blue　analogue　(CoFe　PBA/CF)　electrocatalyst,　adept　at　facilitating　high-concentration　(50　mM)　5-hydroxymethylfurfural　(HMF)　oxidation　into　2,5-furandicarboxylic　acid　(FDCA),　achieving　an　exceptional　HMF　conversion　(100%)　with　a　notable　FDCA　yield　of　98.4%.　The　influence　of　copper　substrate　and　adsorption　energy　are　therefore　discussed.　Impressively,　the　CoFe　PBA/CF　electrode　sustains　considerable　durability　in　a　continuous-flow　electrochemical　reactor　designed　for　consecutive　FDCA　production,　showcasing　FDCA　yields　of　100/94%　at　flow　rates　of　0.4/0.8　mL·min-1　over　60　h’　uninterrupted　electrolysis.　This　work　provides　a　promising　strategy　to　develop　highly　efficient　and　robust　electrocatalysts　for　the　consecutive　production　of　high-value　products　coupled　with　green　H2　production.　©　The　Author(s)　2025.
