Ni-doped MoC in bamboo-like N-doped carbon nanotubes

Corrosion-resistant, highly active

The N-doped carbon nanotube chain mail protects the highly reactive Ni-doped MoC core from alkaline electrolyte corrosion and tunes catalytic activity via charge redistribution, addressing the instability of molybdenum carbide in alkaline water electrolysis.
