However, the intrinsic activity of active sites in MOFs and their derivatives is often not satisfactory. In this study, a Platinum-Cerium (Pt-Ce) synergistic modulation approach, through an easily scalable method, was introduced to enhance the performance of Co-MOF derivative in alkaline Hydrogen evolution reaction (HER) and Oxygen evolution reaction (OER). The optimized Pt@Ce 7.5 /Co x Ni y O z nanoarray, compared to those of counterparts, displayed a pronounced decline in HER overpotential to 210 mV at current density of 100 mA·cm -2 (η 100 ), alongside a Tafel slope of 45.5 mV·dec -1 , and better OER performance in the high current density regions. Theoretical calculations indicate that the unique valence electron structures of Pt and Ce redistribute synergistically the electron cloud density around the active sites through the strong electron coupling of Pt 5d, O 2p, and Ce 4f orbitals, further optimize the Gibbs free energy of adsorbed hydrolysis intermediates. This work would be of some benefit for the design and fabrication of high-performance MOFs derivatives, through a simple and easily scalable production route, Supplementary Material File (synergistic modulation to the electronic structure of mofs2.docx) Download 3.09 MB Information & Authors Information Version history V1 Version 1 10 February 2026 Copyright This work is licensed under a Non Exclusive No Reuse License.
