Lignin-Directed Construction of Vertical Ru/RuO 2 Electron–Bridge Interfaces for Low-Input Self-Powered Hydrazine-Water Splitting

Jianglin Liu, Jinhui Zhang, Liheng Chen, Yanlin Qin et al.

Short summary

A novel Ru/RuO2@HLC catalyst, constructed using lignin to direct Ru/RuO2 heterojunction formation within a carbon matrix, achieves a hydrogen evolution reaction (HER) current density of 50 mA cm–2 at a low 12 mV overpotential, surpassing commercial Pt/C and enabling self-powered hydrazine splitting with a cell voltage of only 0.14 V at 100 mA cm–2.
