• Three types of Ni₃Si₂ were successfully fabricated by low-pressure all-solid melting-reconstruction chemical vapor deposition, and the growth pattern changed with the carbon source content.

• In a carbon-rich atmosphere, high-energy atoms bombard the Ni and Si surface, and reduce the free energy in the solid Ni–Si particles’ thermodynamic equilibrium, considerably catalyzing the growth of Ni–Si nanocrystals.

• Ni₃Si₂/NiOOH/graphene provides a large specific area and NiOOH inhibits insulation on the electrode surface in an alkaline solution and accelerates the electron exchange rate.
