Abstract:
The synthesis and chemical oxidation of metal and binary intermetallic nanoparticles was studied. Specifically, the syntheses of Ni3Sn4 and Bi3Ni were successfully conducted using edible plant and seed oils. A solvent recyclability study of safflower oil was also conducted using the Ni3Sn4 system. Sodium nitrite (NaNO2) was used to fully oxidize metal nanoparticles of Pb, Sn, and In and partially oxidize Bi and Te; generally, the particle morphology was retained during the oxidation. Powder XRD and TEM confirmed the successful oxidations. β-In3Sn was then oxidized with NaNO2 to yield indium tin oxide nanoparticles. Again, the particle’s morphology was maintained throughout the oxidation. Powder XRD, SEM, and TEM confirmed the successful oxidation of β-In3Sn to indium tin oxide.
