Abstract: The present study uses wet-chemical synthesis of highly crystalline single-phase Ni3Sn nanoparticles in DO19 structure. Because of their high mechanical strength and high melting point, DO19 structured intermetallic compounds (IMCs) have become an interesting candidate for robust catalytic activities, which might be further enhanced at lower dimensions. Highly crystalline samples were synthesized using four different surfactants, namely, polyvinylpyrrolidone (PVP), citric acid, sodium dodecyl sulfate (SDS) and pyrogallol. It was found that single phase Ni3Sn could only be obtained in the case of PVP and SDS, while for citric acid and pyrogallol, secondary phases of Ni3Sn2 and Ni were also obtained, respectively. Surface morphology of the samples without any surfactant showed a layered structure. Use of PVP and SDS resulted in the formation of nanorods and random nanoparticles, respectively. X-ray photoelectron spectroscopy analysis showed the presence of metallic Ni and Sn in Ni0 and Sn0 state along with some traces of Ni2+, Sn2+ and Sn4+ that could have formed due to the oxidation of Ni and Sn atoms at the surface of nanoparticle. The present report suggests that other DO19 IMCs could also be synthesized using a similar approach. © 2019, The Minerals, Metals & Materials Society.
