CO Sensing Properties of Chemiresistive In₂O₃/SnO₂ Composite Nanoparticle Sensors.

In₂O₃/SnO₂ composite nanoparticles (NPs) were synthesized by a hydrothermal method. Fringes and spotty patterns were observed in high-resolution TEM images and corresponding selected area electron diffraction pattern, respectively, suggesting the nanoparticles were single crystals. X-ray diffraction results revealed that the In₂O₃/SnO₂ composite NP sensor consisted of three phases: In₂O₃, SnO₂ and In₂Sn₂O (indium tin oxide: ITO).

NO sensing properties of WO-decorated InO nanorods and InO-decorated WO nanorods.

InO nanoparticle (NP)-decorated WO nanorods (NRs) were prepared using sol-gel and hydrothermal methods. The InO NRs and WO NPs were crystalline. WO NP-decorated InO NRs were also prepared using thermal evaporation and hydrothermal methods.
