我国科学家在MOFs电极规模化制备及电解水应用方面取得新进展

Core Insights - The research team led by Zhao Shenlong at the National Center for Nanoscience and Technology has made significant breakthroughs in the scalable preparation of metal-organic framework (MOFs) electrodes for alkaline water electrolysis, as published in the journal Nature Chemical Engineering [1][2]. Group 1: Research Achievements - The team has developed a room-temperature electrodeposition process that allows for the rapid synthesis of large-area MOFs electrodes (400 cm²) within minutes, which are then applied in alkaline water electrolysis systems [2]. - The newly developed MOFs electrodes demonstrate an impressive electrolysis energy consumption as low as 4.11 kWh Nm−3 H2 and can maintain stable operation for up to 5,000 hours [2]. Group 2: Technical Innovations - The superior performance of the MOFs electrodes is attributed to a unique bimetallic structure created by the incorporation of cerium (Ce), which enhances the chemical adsorption of key oxygen-containing intermediates and accelerates the kinetics of the anodic oxygen evolution reaction [2]. - Unlike traditional inorganic catalysts that struggle to balance high activity with scalable production, the CoCe-MOFs electrodes achieve a synergistic breakthrough in efficiency, stability, and cost through electronic structure modulation and rapid scalable preparation strategies [2].
