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/cm2s. 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.
