“…The aim of this work was to investigate the possibility of synthesis, along with the catalytic properties, of AgNi nanoparticles. For this purpose, different methods, including laser ablation [ 30 ], reduction by green plant extracts [ 31 , 32 ], chemical reduction by NaBH 4 [ 33 , 34 ], and solvothermal processes [ 35 , 36 ], may be applied. There are many works devoted to the synthesis of AgNi nanoparticles.…”

This publication presents the synthesis of core–shell nanoparticles, where the core was Ni, and the shell was a Ag–Ni nano alloy. The synthesis was based on the reduction of Ni and Ag ions with sodium borohydride in the presence of trisodium citrate as a stabilizer. In order to determine the phase composition of the obtained nanoparticles, an XRD study was performed, and in order to identify the oxidation states of the nanoparticle components, an XPS spectroscopic study was performed. The composition and shape of the particles were determined using the HR-TEM EDS test. The obtained nanoparticles had a size of 11 nm. The research on catalytic properties was carried out in the model methylene blue reduction system. The investigation of the catalytic activity of colloids was carried out with the use of UV–Vis spectrophotometry. The Ag–Ni alloy was about ten times more active than were pure silver nanoparticles of a similar size.
