Nitrogen‐Plasma‐Activated Hierarchical Nickel Nitride Nanocorals for Energy Applications

Developing transition metal nitrides with unique nanomorphology is important for many energy storage and conversion processes. Here, a facile and novel one‐step approach of growing 3D hierarchical nickel nitride (hNi 3 N) on Ni foam via nitrogen plasma is reported. Different from most conventional chemical synthesis, the hNi 3 N is obtained in much shorter growth duration (≤15 min) without any hazardous or reactive sources and oxide precursors...
