  • A semiconductor metal oxide nanowires (SMO-NWs) shows potential for novel gas sensor applications because of its distinct properties, such as high ratio of surface area to volume, high crystallinity, and perfect pathway forelectron transfer (length of NW). SMO-NW sensors can be configured as resistors or field-effect transistors for gas detection, and different configurations, such as single NW, multiple NWs, and networked NW films, have been established. A surface-functionalizing NWs with catalyst elements and a self-heating NWs provides other options for highly selective andlow-power consumption gas sensors. However, an appropriate design and integration of SMO-NWs should also be ...

  • The synthesis of porous metal-oxide semiconductors for gas-sensing application is attracting increased interest. In this study, α-Fe2O3 hollow balls were synthesized using an inexpensive, scalable, and template-free hydrothermal method. The gas-sensing characteristics of the semiconductors were sys-tematically investigated. Material characterization by XRD, SEM, HRTEM, and EDS reveals that single-Phase α-Fe2O3 hollow balls with an average diameter of 1.5mm were obtained. The hollow balls were formed by self assembly of α-Fe2O3 nanoparticles with an average diameter of 100 nm. The hollow structure and nanopores between the nanoparticles resulted in the significantly high response of th...
