A sodium octadecyl sulfate (SOS) monolayer serves as an anionic interfacial template, enabling the preorganization of protonated 5-aminoquinoline (5-AQ) monomers through electrostatic interactions prior to oxidative polymerization. The resulting two-dimensional PAQ (2D-PAQ) exhibits an anisotropic layered architecture with a densely packed upper layer and a porous lower layer.

Herein, we report an oxygen-vacancy-rich Cu<ce:glyph name=\"sbnd\"></ce:glyph>Ag bimetallic electrocatalyst (CuAg-IH) prepared via rapid induction heating. During the electrocatalytic reduction of HMF, the CuAg-IH catalyst enables a spatially decoupled dual-site mechanism: the stable Ag sites serve as an efficient “proton pump” to accelerate water dissociation for generating abundant active hydrogen (*H), while the induction-heating-induced Cu-Ov sites not only specifically and strongly anchor and polarize the carbonyl group of HMF, but also provide a low-barrier proton-transfer pathway, thereby significantly accelerating the transfer of *H to adjacent Cu sites for targeted reduction. Operando X-ray absorption near-edge structure (XANES) spectroscopy and kinetic isotope effect (KIE) analyses are consistent with reversible interfacial electron enrichment at the Ag-CuOv interface under operating conditions. Consequently, in a neutral 0.5 M PBS electrolyte, the CuAg-IH catalyst achieves the complete conversion of 50 mM HMF at exceptionally low potentials (−0.25 to −0.30 V vs. RHE) with nearly 100% BHMF yield and Faradaic efficiency. Even more impressively, thanks to vacancy-enhanced *H supply and strong substrate activation, at higher substrate concentrations, performance remained close to 100% at 100 mM HMF, while the BHMF yield remained at approximately 80% at 200 mM. This study highlights the unique advantages of induction heating technology in constructing non-equilibrium synergistic interfaces, providing an efficient and feasible strategy for designing catalysts for the electrocatalytic refining of biomass.","PeriodicalId":270,"journal":{"name":"Chemical Engineering Journal","volume":"52 1","pages":"182784"},"PeriodicalIF":15.1,"publicationDate":"2026-10-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149123227","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
