Resumen:
The effect of the support shape on the deposition ofZrO2 by the vacuum-assisted dip-coating method was studied. Disc-shapedand tubular porous stainless steel substrates were used to obtain ZrO2coated supports for the synthesis of PdAu alloy composite membranes. Themicrostructure of the ZrO2 modified supports was evaluated by scanningelectron microscopy and confocal laser microscopy. Besides, a qualitativeassessment of the porosity and roughness of the porous substrates was performedby confocal laser microscopy. Dense and continuous palladium-alloy films were depositedon top of the modified tubes after thirteen ZrO2 deposition-calcinationcycles. Cross-section EDS mapping and XRD diffraction analysis showed that acomplete PdAu alloy formation was obtained even after annealing at 723 K in hydrogen stream during 5 days.
