## Description

- description: The electrochemical oxidation of 5-hydroxymethylfurfural (HMFOR) in
    alkaline electrolyte is a promising strategy for producing high-value chemicals
    from biomass derivatives. However, the disproportionation of aldehyde groups under
    strong alkaline conditions and the polymerization of HMF to form humic substances
    can impact the purity of 2,5-furandicarboxylic acid (FDCA) products. The use of
    neutral electrolytes offers an alternative environment for electrolysis, but the
    lack of OH− ions in the electrolyte often leads to low current density and low
    yields of FDCA. In this study, a sandwich-structured catalyst, consisting of Ru
    clusters confined between unilamellar MnO2 nanosheets (S-Ru/MnO2), was used in
    conjunction with an electrochemical pulse method to realize the electrochemical
    conversion of 5-hydroxymethylfurfural into FDCA in neutral electrolytes. Pulse
    electrolysis and the strong electron transfer between Ru clusters and MnO2 nanosheets
    help maintain Ru in a low oxidation state, ensuring high activity. The increased
    *OH generation led to a groundbreaking current density of 47 mA/cm2 at 1.55 V
    vs. reversible hydrogen electrode (RHE) and an outstanding yield rate of 98.7
    % for FDCA in a neutral electrolyte. This work provides a strategy that combines
    electrocatalyst design with an electrolysis technique to achieve remarkable performance
    in neutral HMFOR.
