“…Transition metal phosphides are becoming promising electrocatalysts because phosphorus can capture protons and promote the formation of peroxide intermediates. The FeCoP amorphous alloy nanoarrays were prepared by electrochemical deposition on nickel foam 78 as shown in Figure 7(g). The composition of the amorphous alloy is controlled by changing the concentration of the metal salts in the solution.…”

The energy crisis put forward higher requirements for the development of sustainable energy systems, and the production of green hydrogen by electrochemical water electrolysis is one of the important ways to achieve this goal. Transition metal amorphous alloys have been widely investigated as efficient electrocatalysts for water electrolysis. However, the low catalytic activity, high cost, lack of multifunction, poor stability, and unclear catalytic mechanism on amorphous alloy electrocatalysts have severely limited their efficiency. In this review, we summarize the recent progress on amorphous alloys. Specifically, the characteristics, structure, and preparation methods of amorphous alloys and their application, especially in water electrolysis, are discussed in detail. On the basis of the function-oriented design and the solution of key problems, the electrocatalytic performance has been effectively improved in quantity and quality. In the future, studies should focus on the aspects of controlling material morphology, element doping, composite structure, and interface characteristics, as well as the structure–activity relationship and synergetic effect. This review is of great significance to promote the study of structural design, structure–activity relationship, efficiency improvement, and catalytic mechanisms in electrocatalysis.

“…Moreover, numerous studies report on the fabrication of Fe-Co-P alloys by different techniques such as reacting low-reactive metal-oleates (Co 2+ and Fe 3+ ) with trioctylphosphine [33], electrodeposition [34,12], drop synthesis method [36], organic phase reaction [37,38], phase-solution method [39], and electroless plating method [40]. Herein, it is important to highlight that phosphorus was added to FeCo alloy to improve the soft magnetic performance of the mixture the magnetic permeability as well as provides strengthening to the solid solution within the matrix [41,42].…”

This research work aims to investigate the mechanically alloyed Fe15Co2P3. Parametric Rietveld refinement method, of the obtained X-ray patterns, was performed for qualitative and quantitative phase analysis, structural, microstructural and mechanical properties. The ball-milled powder mixture crystallized within the face-centred cubic α-Fe(P) solid solution in equilibrium with Co75Fe25 phase. The crystallite size decreases reaching 100 and 200 nm respectively after 3h of milling. The highest values of the dislocation density, microstain and stored energy are registered for the α-Fe(P) solid solution. The studied mechanical properties manifest the brittle nature of the α-Fe(P) solid solution compared to the Co75Fe25 phase. The squareness ratio Mr/Ms and the coercivity values of the milled powders increase with increasing milling time and reach steady state after 2 h. The hysteresis loss energy and maximum permeability reach minimal values of 45*10− 4 W/m3 and 49*10− 3 H/m respectively, after 1 h of milling at the opposite of the switching field distribution.

This research work aims to investigate the mechanical alloying of Fe 15 Co 2 P 3 powder mixture in terms of phases' formation, microstructural parameters, and magnetic properties as function of milling time. Parametric Rietveld refinement method, of the obtained X-ray patterns, was performed for qualitative and quantitative phase analysis alongside the determination of structural, microstructural, and mechanical properties. The ball-milled powder mixture crystallized within the face-centered cubic α-Fe(P) solid solution in equilibrium with Co 75 Fe 25 phase. The crystallite size decreases reaching 100 and 200 nm respectively after 3 h of milling. The highest values of the dislocation density, microstrain, and stored energy are registered for the α-Fe(P) solid solution. The studied mechanical properties manifest the brittle nature of the α-Fe(P) solid solution compared to the Co 75 Fe 25 phase. The squareness ratio M r /M s and the coercivity values of the milled powders increase with increasing milling time and reach steady state after 2 h. The hysteresis loss energy and maximum permeability reach minimal values of 45 × 10 −4 W/m 3 and 49 × 10 −3 H/m respectively, after 1 h of milling at the opposite of the switching field distribution. The obtained results demonstrate the formation of nanostructured Fe 15 Co 2 P 3 ternary alloy with optimum characteristics as promising candidate for diverse applications primarily in the biomedical field for diagnostics and therapeutics such as magnetic hyperthermia and vector probes for future imaging technologies.
