Abstract: ABSTRACT 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 67 Pd 33 /TTATP, which converted HMF → FDCA in water using atmospheric O 2 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 2 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.
