Oxygen Sensing Properties of Platinum Doped Indium Oxide Nanoparticles Prepared by Hydrothermal Method

Indium oxide (In2O3) and platinum doped (in situ method) indium oxide (Pt-In2O3) nanoparticles were prepared by surfactant assisted hydrothermal route followed by calcination at 400°C. The X-ray diffraction data revealed that the average size of the nanoparticles was around 15 nm and the transmission electron microscopic investigation showed that the nanoparticles were formed as short nanorods. The oxygen sensing ability of the sensors...
