Abstract

Porous intermetallic Ni₂XAl (X = Ti or Zr) nanoparticles with small crystallite sizes (24-34 nm) and high Brunauer-Emmett-Teller (BET) surface areas (10-71 m² g^-1) were prepared from oxide precursors by a chemical route. CaH₂ acted as a template to form the porous morphologies and assisted the reduction.
