Microstructure and sensing properties of nanocrystalline indium oxide prepared using hydrothermal treatment

Nanocrystalline indium(III) oxide samples were prepared using soft chemistry. The microstructure (particle size and shape, specific surface area, pore-size distribution) and sensing properties of In2O3 were studied as functions of synthesis parameters. Indium oxide synthesis including hydrothermal treatment produces materials having high sensing sensitivity in NO2 detection.
