This article describes the synthesis and characterization of tin-doped indium oxide (ITO) and platinum nanoparticles deposited on ITO. For different calcination temperatures, the tin-doped indium oxide nanoparticles (ITO NPs) were synthesized successfully by a nonaqueous sol-gel method with indium acetylacetonate and tin bis(acetylacetonate) dichloride in oleylamine as the precursors. The ITO sample that calcinated at 500 °C exhibited a spherical morphology with a narrow range of the particle size distribution (15-20 nm). Moreover, the electrical conductivity of the sample (1.242 S/cm) was higher than many different non-carbon supports. In addition, 20% platinum nanoparticles (Pt NPs) were also deposited uniformly on the ITO supports via chemical reduction process using NaBH4 as the reducing agent. The size of Pt NPs was about 5 nm and the crystalline structure of ITO supports remained unchanged. |
