Pd-based binary and ternary alloy membranes: Morphological and perm-selective characterization in the presence of H2S
(Elsevier, 2013-09)
Pd, Pd90Ag10, Pd91Au9, Pd78Ag9Au13 and Pd75Ag16Au9 alloy membranes were prepared on vacuum-assisted ZrO2-modified porous stainless steel supports by sequential electroless deposition. The membranes were evaluated for ...
Hydrogen permeation and surface properties of PdAu and PdAgAu membranes in the presence of CO, CO2 and H2S
(Elsevier Science, 2018-10-01)
Using the electroless deposition technique with different deposition sequences, it was possible to obtain a single phase PdAgAu ternary alloy after treatment at 773 K during 7 days. Despite the order of deposition, the ...

Different oxides used as diffusion barriers in composite hydrogen permeable membranes
(Elsevier Science, 2006-04)
Composite Pd-Ag membranes supported on modified porous stainless steel substrates were prepared by sequential electroless plating. To improve the stability of the Pd-Ag alloy, two different intermediate layers of α-Fe2O3 ...
PdAgAu alloy with high resistance to corrosion by H2S
(Pergamon-Elsevier Science Ltd, 2012-09)
PdAgAu alloy films were prepared on porous stainless steel supports by sequential electroless deposition. Two specific compositions, Pd83Ag2Au15 and Pd74Ag14Au12, were studied for their sulfur tolerance. The alloys and a ...

Alloying and surface composition of model Pd-Ag films synthesized by electroless deposition
(Pergamon-Elsevier Science Ltd, 2012-04)
PdAg model films and real composite membranes were prepared by sequential electroless deposition on top of porous stainless steel supports. Their surface properties were investigated by X-ray photoelectron spectroscopy ...
Novel PdAgCu ternary alloy as promising materials for hydrogen separation membranes: Synthesis and characterization
(Elsevier Science, 2011-01)
The use of the sequential electroless plating method allowed us to obtain the PdAgCu ternary alloy on top of dense stainless steel (SS) 316 L disks. The XRD analysis indicated that initially the nucleation of the two phases ...
