Single-step large-scale and template-free electrochemical growth of Ni-Zn alloy filament arrays from a zinc chloride based ionic liquid

For the first time, direct template-free electrodeposition of aligned NiZn nanofilaments was achieved on a tungsten substrate in a quiescent Lewis acidic ZnCl2-EMIC ionic liquid containing NiCl2 at 150 degrees C by applying an extremely large deposition overpotential.
