“…During metal electrodeposition, it is frequently found that the number of nucleation sites increases in the presence of the field, irrespective of its orientation. [33,36] Electrodeposition performed on TEM grids by Ustarroz et al has shown that the nucleation sites originate from the assembly of tiny mobile subnuclei. [37] Therefore, the fact that experiments performed in magnetic fields produce a larger number of particles would imply that the early nuclei are somehow stabilized by the field, with growth setting in before they are able to assemble.…”

“…Budevski et al) [71] -is that electroactive ions are reduced at the electrode surface, yielding adatoms that move around on the surface, mainly under surface diffusion, but potentially under different force fields, [72] forming aggregates with different stabilities [73] and eventually ending up incorporated in the solid in correspondence of an energetically favourable site. In the case of polymer electrodeposition, the electrochemical phase formation involves partly different physical chemistry: as a representative example, the following scheme has been proposed in the study of Milchev and Staikov.…”

In this paper, we report on the use of high-space resolution soft X-ray fluorescence microspectroscopy for the study of electrodeposited composites containing catalytic ternary metal nanostructures. X-ray fluorescence maps are interpreted in terms of a dynamic mathematical model of the electrode morphology and metal space distribution, allowing to reproduce the observed space patterns and electrochemical transients by assigning an appropriate set of electrokinetic parameters. The discussed materials-science case is the electrochemical growth of a Mn-Mg-Cu-polypyrrole nanocomposite electrocatalyst material -free of expensive Pt and environmentally unfriendly Co -with promising performance for fuel-cell oxygen electrodes. The synergy of high-resolution compositional mapping with electrokinetic modelling not only provides the general rationale for quantitative use of potentially large compositional distribution datasets but also yields unprecedented insight into the specific catalyst synthesis process. The expounded application is just a prototypical case study of a more general approach, which can be employed for the understanding of electrochemical material science processes, both in situ and ex situ, as well as for the characterisation of the corresponding products, with no other limitations in principle than X-ray transmission and beam damage.

“…The influence of an external magnetic field on the electrochemical deposition of metals such as Co, Fe, Ni, and its alloys on a flat electrode was mainly investigated [14][15][16][17][18][19][20][21][22][23][24]. So far, limited studies have been done to examine the influence of the magnetic field applied during cobalt deposition into Al 2 O 3 pores on the magnetic properties of the cobalt nanowires, and previous studies had not provided clear results [25][26][27].…”

Cobalt nanowires were obtained in the process of electrodeposition into pores of an alumina membrane. Structural research (XRD, TEM) of Co revealed the facecentered cubic structure. However, the existence of the hexagonal structure cannot be excluded due to strong texture. The influences of an external magnetic field and Al 2 O 3 membrane geometry on magnetic properties of obtained wires were examined. It was found that cobalt nanowires exhibit pronounced shape anisotropy in a direction parallel to the wire axis. The highest influence on the magnetic properties is ascribed to the nanowires geometry i.e., height, diameter, and distances between single wires. Application of an external magnetic field in a perpendicular direction to the sample surface during cobalt electrodeposition increases magnetic anisotropy with a privileged direction along the wire axis. Application of the magnetic field in a parallel direction to the sample surface changes the direction of magnetization.
