Hydrogen Permeability of NiO-Doped Alumina with Nickel Composites Membrane

Article Preview

Abstract:

NiO-doped Al2O3 was synthesized with 20 wt% of nickel nitrate using the sol-gel process. P123 as an organic additive added to increase surface area of powder. The phase transformation, thermal evolution and surface morphology of the powder were characterized by XRD, TG-DTA and FE-SEM. The 20 wt% NiO-doped Al2O3 /10 wt% Ni composite membrane was prepared by hot press sintering (HPS) following with a mechanical alloying process. Hydrogen permeation flux for 20 wt% NiO-doped Al2O3 /10 wt% Ni membrane was obtained as 0.1 mol/m2 s at 673K.
