南京大学杨立军/吴强最新AM丨Ru-MoC界面加速碱性析氢！

TL;DR - A phase-engineered Ru–MoC heterointerface accelerates alkaline hydrogen evolution by improving water dissociation and separating OH* from Ru active sites. The catalyst outperformed commercial Pt/C and supported industrial-scale current density in a membrane electrolyzer.

• Ru–MoC/hNCNC required only 20 mV overpotential to reach 10 mA cm⁻² in 1 M KOH.
• Mo vacancies promote strongly coupled, disordered Ru clusters and Ru–Mo coordination at the interface.
• Raman spectroscopy and DFT indicate that water splits at Mo sites, with OH retained on MoC and H formed on Ru, reducing Ru poisoning.
• An AEM electrolyzer using the catalyst reached 1 A cm⁻² at approximately 1.65 V.
