Synergistic Alloy and Support Effects in Covalent Organic Framework‐Stabilized AuPd Catalysts for Aerobic 5‐Hydroxymethylfurfural Oxidation to 2,5‐Furandicarboxylic Acid
Catalytically converting 5-hydroxymethylfurfural (HMF) to 2,5-furandicarboxylic acid (FDCA) underpins renewable, bio -based plastics, yet designing metal-efficient catalysts remains challenging. Here, we combine alloy and support effects by anchoring AuPd alloy nanoparticles on 2D covalent organic frameworks (COFs). Rationalizing alloy composition and COF functionality yielded Au<sub>67</sub>Pd<sub>33</sub>/TTATP, which converted HMF → FDCA in water using atmospheric O<sub>2</sub> mild conditions, delivering >99% FDCA yield, stable reusability, a turnover number (TON) of ∼100 at HMF/metal = 100, increasing to 518 at 600 (86.4% yield). High performance stems from alloy-support synergy that (i) partitions function (Au: HMF dehydrogenation; Pd: O<sub>2</sub> activation) and (ii) matches adsorption-desorption (TTATP enriches HMF yet releases FDCA; alloy surfaces moderate HMF binding and avoid the strong FDCA adsorption of Pd alone), thereby enhancing metal atom efficiency.
