“…Various synthesis methods have been employed for production of these alloys; including high vacuum sputtering [13], pulsed laser deposition [14], epitaxial vapor deposition [8], floating zone [15] and electrodeposition [4][5][6][7][16][17][18][19][20][21][22]. Not only electrodeposition process is favorable from the economical point of view, but also it brings the possibility of controlling chemical composition [7,16,20].…”

“…A literature survey shows that various substrates have been employed in Fe-Pd alloy electrodeposition including titanium [17], copper [18], platinum [19], brass [20], gold [21], and stainless steel [20]. However, less attention has been paid to the effects of substrate on the kinetics of electrodeposited films from electrochemical point of view [16][17][18][19][20][21]. For instance, Hernandez et al evaluated the effect of different substrates (Au/Si, brass and stainless steel) on the chemical composition, magnetic properties and morphology of Fe-Pd alloy films [20].…”

In this work, Fe-Pd alloy films have been electrodeposited on different substrates using an electrolyte containing [Pd(NH 3) 4 ] 2 + (0.02 M) and [Fe-Citrate] 2 + (0.2 M). The influences of substrate and overpotential on chemical composition, nucleation and growth kinetics as well as the electrodeposited films morphology have been investigated using energy dispersive X-ray spectroscopy (EDS), current-time transients, scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD) patterns. In all substrates-brass, copper and sputtered fluorine doped tin oxide on glass (FTO/glass)-Fe content of the electrodeposited alloys increases by increasing the overpotential. Also the cathodic current efficiency is low due to high rate of H 2 co-reduction. Regarding the chronoamperometry current-time transients, it has been demonstrated that the nucleation mechanism is instantaneous with a typical three dimensional (3D) diffusion-controlled growth in the case of brass and copper substrates; while for FTO, the growth mode changes to 3D progressive. At a constant overpotential, the calculated number of active nucleation sites for metallic substrates is much higher than that of FTO/glass; however by increasing the overpotential, the number of active nucleation sites increases. The SEM micrographs as well as the XRD patterns reveal the formation of Fe-Pd alloy thin films with nanostructure arrangement and ultrafine grains.

“…Because of the large difference of 1.4 V [2] in the standard reduction potentials of Fe 2+ and Pd 2+ , different complexing agents have to be used in order to make the co-deposition of both metals possible. As a result, Fe-Pd thin films were successfully deposited from ammonium tartrate- [3], sulfate- [4] and citrate-based [5,6] baths.…”

“…For example, electrodeposited Ni-P can form solid solutions containing phosphorus levels of 10 wt.% or more [29,30]. Similarly, extended solubility ranges were also observed in other alloys, such as Co-W [31], Zn-Ni [32], Ni-Mo [33], Fe-Pd [34]. Moreover, new phases may form in nanostructured alloys fabricated by electrodeposition; for example, highly textured thin films of nonstoichiometric NiWO 4 were formed during co-deposition of nickel and tungsten [35].…”

Background: Quasi-one dimensional nanostructures: nanowires, nanotubes, nanorods, nanobelts/nanoribbons and complex "nanowire-nanoparticle" composites have been synthesized over the years. These nanostructures are particularly appealing due to their specific properties defined by their high aspect ratio: two dimensions are in the nanoscale range and one dimension is in the microscale. Methods:One of the well-designed approaches for the synthesis of such nanostructured materials is template-assisted fabrication combined with electrodeposition. The fabrication approaches for the growth of iron-group alloy nanostructures inside nanoporous oxide membranes by means of different electrodeposition techniques, and the resulting unique properties and potential applications of this type of materials are reviewed. Results:Arrays of nanostructures can be obtained by filling a porous oxide template that contains a large number of straight cylindrical, nano-sized diameter holes. Generalities of metals electrodeposition into nanoporous oxide membranes are discussed. Measures to minimize the nonuniformity of deposits inside pores need to be addressed to thin the barrier layer, to control hydrogen evolution and to improve mass transport inside the pores. Examples of binary and ternary iron group alloys grown inside nanoporous oxide templates are provided. Catalytic hydrogen evolution and methanol oxidation on the nanowires arrays are described. The "sample size effect" on the magnetic properties of materials and the electrodeposition of multilayered structures necessary for giant magnetoresistance (GMR) are discussed in details. Conclusion:Electrodeposition of binary and ternary iron-group alloys confirm that controlling alloy composition inside nanopores is still a challenge. composites [7] have been synthesized over the years. These nanostructures are particularly appealing due to their specific properties defined by their high aspect ratio: two dimensions are in the nanoscale range and one dimension is in the microscale. One of the well-designed approaches for the synthesis of such nanostructured materials is template-assisted fabrication combined with electrodeposition, first reported by Possin [8] in track etched mica films, and expanded upon by others with different materials and templates [2,[9][10][11][12][13][14]. However, the self-organized porous anodic aluminum oxide (AAO) membrane has become one of the most often used templates for tunable synthesis of different nanostructured materials [15,16].
