- •
NiOx-Pt/C showed higher activity than Pt/C or NiOx/C.
- •
Bifunctional mechanism played important role lowering the reaction onset potential.
- •
H2 decreases and N2 increases in DEMS concomitantly with the faradaic current.
- •
Separated potential domains of complete and incomplete hydrazine electrooxidation.
