Three distinct graphitic substrates were subjected to controlled electrochemical treatments utilizing sodium sulfate or phosphoric acid as electrolytes. The process expanded the graphite particles/pieces and introduced oxygenated functional groups to the exposed surfaces while preserving the structural integrity of the bulk material. The resulting modifications influenced the type and quantity of Lewis and Brønsted acidic sites, providing exhaustive control over reaction pathways leading to HMF. This electrochemically modified graphite demonstrated superior tunability compared to traditional metal-based catalysts, enabling dynamic optimization of reaction conditions for enhanced HMF yield. The controlled introduction of functional groups facilitated the tailoring of active sites, significantly impacting the kinetics of glucose conversion and achieving HMF selectivity up to 95%. This level of precision in controlling catalytic properties is essential for maximizing HMF yield while minimizing undesired by-product formation, addressing a critical challenge in HMF production. info:eu-repo/grantAgreement/ES/MICINN/FEDER/PID2020-113809RB-C32 info:eu-repo/grantAgreement/ES/MICINN/PID2020-113809RB-C31/AEI/10.13039/501100011033 info:eu-repo/grantAgreement/ES/MINECO/BES-2016-077830 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 6.9 2024 MATERIALS SCIENCE, COATINGS & FILMS 3 / 24 = 0.125 2024 Q1 T1 PHYSICS, CONDENSED MATTER 16 / 80 = 0.2 2024 Q1 T1 PHYSICS, APPLIED 33 / 187 = 0.176 2024 Q1 T1 CHEMISTRY, PHYSICAL 47 / 185 = 0.254 2024 Q2 T1 1.31 2024 Chemistry (miscellaneous) 2024 Q1 Condensed Matter Physics 2024 Q1 Surfaces, Coatings and Films 2024 Q1 Surfaces and Interfaces 2024 Q1 Physics and Astronomy (miscellaneous) 2024 Q1 13.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Bounoukta, Charf Eddine Ivanova, Svetlana Centeno, Miguel Ángel Villar-Rodil, Silvia Paredes, Juan Ignacio (orcid)0000-0001-9220-9909 Cazaña, Fernando Universidad de Zaragoza (orcid)0000-0002-7836-5777 Monzón, Antonio Universidad de Zaragoza García-Dalí, Sergio 5005 555 Universidad de Zaragoza Dpto.
