Large-scale synthesis of Au–Ni alloy nanowires using electrochemical deposition

Abstract

The template-assisted electrodeposition technique has been utilized to synthesize highly ordered, wellaligned, and dense Au-Ni alloy nanowires. The electrochemical impedance spectroscopy has been carried out to study the in situ growth process of alloy nanowires at different electrodeposition times. Their morphological studies have been carried out using the high-resolution transmission electron microscopy. Elemental composition of template-synthesized nanowires has been studied by energy dispersive X-ray analysis. The X-ray diffraction study revealed the face centered cubic structure of the nanowires. Magnetic properties of the nanowires have been studied using Quantum Design vibrating sample magnetometer.

Prediction of a low-temperature N 2 dissociation catalyst exploiting near-IR–to–visible light nanoplasmonics

“…It is noteworthy that well-mixed alloys of Au and first-row transition metals such as Ni, Co, and Fe, which are also immiscible in Au (31)(32)(33), can be synthesized electrochemically via simultaneous reduction of the dopants and Au erosion (34), and electrodeposition using salts of Au and of the dopants (35). Large-scale synthesis of dense Au-Ni alloy nanowires was achieved using an electrodeposition technique (36). Laser ablation was also successfully deployed to synthesize nanoalloys of Au and Fe (37).…”
