“…The metal/metal−halide weight ratio of 7:1, according to our previous findings from over 10 repetitions of the experimental trials, 28 was proposed as the optimum volume-to-mass ratio to consistently produce the nanoalloys using this system. 35 The dimethylformamide (DMF) organic solvent with the formula C 3 H 7 NO (purity: 99.8%, pH = 6.7) from Chem-Supply Pty Ltd. was proposed as the reaction medium due to its high boiling point (153 °C), which remains stable for the temperature range in which the ultrasonication cycle takes place, demonstrating great capability to form a stable Ga-rich suspension of LM nanoparticles during mechanical agitation. Furthermore, due to its polar nature, DMF contributes to the coreduction of the silver salts, 36−38 performing a dual role as a AgF reducing agent and a reaction solvent.…”

Silver (Ag) nanoalloys play significant roles in several industrial applications. While still many sustainable frameworks can be explored for the synthesis and functional incorporations, the control of phase and structure at the nanoscale still is a major challenge for their practical implementation. In this study, liquid-phase gallium (Ga(L)) nano-/microspheres were utilized for this purpose, investigating their function as reaction media and metallic alloying elements for the development of one-dimensional (1D) Ag–Ga nanoalloys from a silver fluoride precursor. Ultrasonic input at near room temperature was selected for the green synthesis method. The mechanisms for the nucleation, anisotropic growth, and morphological development under ultrasonic oscillations were comprehensively analyzed. The experimental outcomes revealed that the development of 1D Ag–Ga nanoalloys was in correlation with the ultrasonic exposure time, influencing the inter-/intraparticle interactions, modulating the Ga(L) nano-/microsphere dimensional and structural properties, and establishing Ag–Ga bimetallic core–shell microsystems accordingly. The subsequent self-assembly mechanisms were observed to have been primarily driven by Ga(L) surface tension and intermolecular forces promoting spontaneous Ag–Ga liquid–solid interfacial wetting and intermetallic diffusion. The nucleation and crystallization of the 1D nanoalloys developed following two possible pathways for the differentiation of morphologies in the form of either nanoneedles or nanorods identified as the Ag2Ga crystal phase. We observed that the key advantage of Ga(L) nano-/microspheres as the reaction media is the direct control of the phase and morphological development of the 1D Ag–Ga batch structures, demonstrating a straightforward route for the green synthesis of engineered nanoalloys for catalytic applications.
