Twin-distortion modulated ultra-low coordination PtRuNi-O catalyst for enhanced hydrogen production from chemical wastewater.

The development of efficient and robust catalysts for hydrogen evolution reaction is crucial for advancing the hydrogen economy. In this study, we demonstrate that ultra-low coordinated hollow PtRuNi-O nanocages exhibit superior catalytic activity and stability across varied conditions, notably surpassing commercial Pt/C catalysts. Notably, the PtRuNi-O catalysts achieve current densities of 10 mA cm at only 19.
