A research team at Tohoku University has developed an Electronic Fine-Tuning (EFT) approach to enhance interactions between zinc and ruthenium, resulting in a highly active and stable catalyst for hydrogen production. By anchoring ruthenium clusters onto hierarchically layered zinc-nitrogen-carbon nanosheets, the team created a material, Ru@Zn-SAs/N-C, that outperforms commercial platinum-based catalysts in both the oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER). The catalyst's superior performance is attributed to the strong electronic metal-support interaction (EMSI) between zinc and ruthenium, which optimizes adsorption energy of critical reaction intermediates. This breakthrough offers a cost-effective alternative to platinum catalysts, showcasing enhanced efficiency in hydrogen production. The research has implications for the affordability and scalability of hydrogen energy, contributing to the development of cost-effective hydrogen fuel cells, water electrolysis systems, and sustainable industrial processes. The team plans to further refine the EFT strategy, improve catalyst stability, and explore applications in zinc-air batteries, fuel cells, and carbon and nitrogen reduction reactions.
