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.
本文描述了锡掺杂氧化铟（ITO）以及沉积在ITO上的铂纳米颗粒的合成与表征。对于不同的煅烧温度，以乙酰丙酮铟和二氯二（乙酰丙酮）锡为前驱体，在油胺中通过非水溶胶 - 凝胶法成功合成了锡掺杂氧化铟纳米颗粒（ITO NPs）。在500℃煅烧的ITO样品呈现出球形形态，粒径分布范围较窄（15 - 20nm）。此外，该样品的电导率（1.242 S/cm）高于许多不同的非碳载体。另外，还通过使用硼氢化钠作为还原剂的化学还原过程，将20%的铂纳米颗粒（Pt NPs）均匀地沉积在ITO载体上。Pt NPs的尺寸约为5nm，ITO载体的晶体结构保持不变。
