In this study, it was aimed to plate PdCu alloy layer on porous glass supports by using
electroless plating technique. It was also aimed to achieve coexistence of fcc (face-centered
cubic) and bcc (body-centered cubic) phases on the alloy membrane layer. The fcc and bcc
phases were seen together in the structures of the membranes synthesized at all three bath
temperatures (30 °C, 40 °C and 50 °C), but, it was shown that the most suitable coating rate
was achieved when the coating bath temperature was 40 °C. The appropriate composition of
PdCu (74% Pd, 26% Cu) was achieved by following a synthesis procedure as follows: Coating
in Pd bath three times for 60 minutes each followed by coating in Cu bath at the low
formaldehyde concentration (5 mL/L) for 15 minutes. Hydrogen flux in the membrane was
measured as 1.9x10-6 mol/cm2
s. After flux measurements, it was determined that the membrane
structure changed and the fcc (200) structure, which did not previously exist in the structure,
was formed.
