Porous intermetallic Ni2XAl (X = Ti or Zr) nanoparticles prepared from oxide precursors†
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.
